Troubleshooting
This page describes problems encountered when setting up and administering the server. Not regularly updated, except perhaps the issues where the cause and/or fix is still unknown.
| Operating system | Ubuntu Server 20.04 LTS |
|---|---|
| Hardware | Intel NUC10i3FNH |
2024-05-10 Friday
| Cannot find Ubuntu kernel headers for building modules | |
| Observations | - |
|---|---|
| Cause | Installation of mainline kernel resulted in a kernel that is not compatible with other kernel libraries built on the corresponding apt repositories. |
| Fix | Either downgrade, or reinstall kernel. For downgrade: grep 'menuentry \|submenu ' /boot/grub/grub.cfg | cut -f2 -d "'", then write to /etc/default/grub GRUB_DEFAULT="Advanced options...>Ubuntu, with Linux...". Delete the kernel with sudo apt purge ... |
2024-02-12 Monday
journalctl spammed with action 'action-0-builtin:omfile' suspended messages |
|
| Observations | sudo journalctl -fx shows this message multiple times, at every minute or so: Feb 12 16:44:31 - rsyslogd[6728]: action 'action-0-builtin:omfile' suspended (module 'builtin:omfile'), retry 0. There should be messages before this one giving the reason for suspension. [v8.2112.0 try https://www.rsyslog.com/e/2007 ] |
|---|---|
| Cause | GitHub comment. Likely because syslog is made to write to a file which it does not have permissions for. Configuration found in /etc/rsyslog.conf and /etc/rsyslog.d/50-default.conf, to see what user is used to write to which log files. In this instance, syslog was not given write permissions to /var/log. |
| Fix | sudo chmod g+w /var/log |
2023-12-11 Monday
nginx and ssh failed |
|
| Observations | |
|---|---|
| Cause | |
| Fix | Reboot services. |
The first log triggering a 504 Gateway Timeout occurred when YandexBot tried to poll https://pyuxiang.com/ at 1.06am on 11 Dec from 213.180.203.29. Tracking backwards:
- Error 499 by PetalBot on Dokuwiki (client stop) at 1.05am
- Error 499 by Vivaldi user (202.142.162.187) on Dokuwiki (/wiki/syntax) at 12.36am
- PHP upstream timed out (110: Unknown error) while reading... upstream:
fastcgi://unix:/var/run/php/php8.1-fpm.sockstarted at 1.06am- 12.36am remote logoff service logs dropped
- An RDP probe was triggered:
\x03\x00\x00/*\xE0\x00\x00\x00\x00\x00Cookie: mstshash=Administrwhich returns a 400- Possible relevant source: https://pastebin.com/PSbQXJYL
- A prior zgrab probe
- Services:
- Nothing wrong with PHP service.
- SSHD logs do not look anomalous.
- Nginx service as well.
No idea.

| High IRQ observed | |
| Observations | Running glances shows a high rate of interrupt requests from 18_i2c_designware.1, around 18kreq/s, similarly visible via cat /proc/interrupts (with log 18: 0 0 889547135 0 IR-IO-APIC 18-fasteoi idma64.1, i2c_designware.1). A corresponding [irq/65-i2c-INT3] is present in the process list as well. sudo powertop corroborates with ~200 interrupts per second by [18] idma64.1 and ~1.8ms/s usage by process 55974 irq/65-i2c-INT3, with corresponding 0.5% CPU load on CPU2. |
|---|---|
| Cause | See forum for answer, reproduced below. Bug filed on Ubuntu but regression observed, likely issue with Linux kernel itself. |
| Fix | Running modprobe -r tps6598x to disable the problematic driver solves this temporarily until a power cycle. |
My guess is that the IRQ resource is not correct for the PD controller causing you to see irq flood.
The problem is that the ACPI device entry (the node) on this platform has 4 I2CSerialBus resources and 4 IRQ resources. The idea is that the single ACPI device entry can represent up to 4 USB PD controllers. The problem is that there is no way to know which IRQ resource belongs to which I2CSerialBus resource.
And, this is one of those multi-instantiate I2C slave devices with HID INT3515.
The only solution I can think of is that we start maintaining DMI quirk table in drivers/platform/x86/i2c-multi-instantiate.c where we supply the correct i2c to irq resource mapping for every platform that has this device(s).

| Docker service failed to start | |
| Observations | See logs below. |
|---|---|
| Cause | Likely due to server shutdown during Docker startup, resulting in corrupted files. |
| Fix | Nuked the whole docker configuration using sudo rm -rf /var/lib/docker as suggested by GitHub. Storing of volumes in local filesystem instead of as a native Docker volume mitigated all the damages. |
See the other following supporting information: [1] [2] [3] [4]
2022-12-26 Monday
| Attempting to access crontab raises SegmentationFault | |
| Observations | Both crontab -e and sudo crontab -e raises SegmentationFault, with no error message. Seems like pip3 is also part of this list now. |
|---|---|
| Cause | Unknown, likely file corruption due to long uptime of non-ECC server. According to SO, is attributable to either crontab itself, a damaged filesystem, or some hardware problem. |
| Fix | Unknown |
| Extensive use of swap memory. | |
| Observations | Server responses became noticeably a lot more sluggish. Checking top and mem-something showed low memory footprint, but swap space is being actively used. No tmpfs occupying space either. |
|---|---|
| Cause | Suspected due to long uptime of server, resulting in a memory leak / dangling memory pointers, etc. |
| Fix | Restart the server. |
| Unable to SSH into system. | |
| Observations | After a couple minutes of uptime, the server stops responding to incoming SSH requests. Connection dropped either due to broken pipes, or kex_exchange_identification: read: Connection reset. |
|---|---|
| Cause | Unknown. |
| Fix | Restart the server. |

Failure to get docker service running |
|
| Observations | See below. |
|---|---|
| Cause | No idea. |
| Fix | See below as well. |
Observations
Changed a FUSE mount target earlier but did not change /etc/fstab.
Tried to restart a docker container (stopped container, edited fstab, mount all mount -a, docker compose up), but failed with following error:
$ sudo docker-compose up -d Starting pigallery2 ... error ERROR: for pigallery2 Cannot start service pigallery2: failed to create shim: OCI runtime create failed: container_linux.go:380: starting container process caused: process_linux.go:385: applying cgroup configuration for process caused: no cgroup mount found in mountinfo: unknown ERROR: for pigallery2 Cannot start service pigallery2: failed to create shim: OCI runtime create failed: container_linux.go:380: starting container process caused: process_linux.go:385: applying cgroup configuration for process caused: no cgroup mount found in mountinfo: unknown ERROR: Encountered errors while bringing up the project.
Quick search indicated potential issue with some cgroupfs mount. Ran the following as suggested here:
# Initially empty directory systemd/ sudo mount -t cgroup -o none,name=systemd cgroup /sys/fs/cgroup/systemd
Did not work. Tried to download the package, but surprising did not do anything.
https://unix.stackexchange.com/questions/249425/cant-run-docker-hello-world-mountpoint-for-devices-not-found sudo apt install cgroupfs-mount
An article suggested containerd was at fault, tried to restart docker service and failed:

Suggests a cgroupfs issue.
Running the following did not work, even with containerd stopped using systemctl:
$ sudo cgroupfs-umount rmdir: failed to remove 'blkio': Read-only file system rmdir: failed to remove 'cpu': Read-only file system rmdir: failed to remove 'cpu,cpuacct': Read-only file system rmdir: failed to remove 'cpuacct': Read-only file system rmdir: failed to remove 'cpuset': Read-only file system rmdir: failed to remove 'devices': Read-only file system rmdir: failed to remove 'freezer': Read-only file system rmdir: failed to remove 'hugetlb': Read-only file system rmdir: failed to remove 'memory': Read-only file system rmdir: failed to remove 'net_cls': Read-only file system rmdir: failed to remove 'net_cls,net_prio': Read-only file system rmdir: failed to remove 'net_prio': Read-only file system rmdir: failed to remove 'perf_event': Read-only file system rmdir: failed to remove 'pids': Read-only file system rmdir: failed to remove 'rdma': Read-only file system rmdir: failed to remove 'systemd': Read-only file system umount: /sys/fs/cgroup/unified: target is busy.
Ran this again, and now the docker is behaving...?
sudo umount /sys/fs/cgroup/systemd sudo mount -t cgroup -o none,name=systemd cgroup /sys/fs/cgroup/systemd
In other words, a big shot in the dark. Very painful. This perhaps helped as well:

| (Duplicate) Same issue as in "Docker containers terminated with exit code 143" | |
| Observations | Attempts to access Seafile server at the address returns 502 Bad Gateway, i.e. the service is likely down. Quick check of journalctl shows termination of docker services at Oct 06 06:20:37. Docker shows certain services are still up and running. |
|---|---|
| Cause | Restart of docker container engine, and containers without restart: always or restart: unless-stopped flags immediately terminate. |
| Fix | Add the restart: always flag to the Seafile server. |

| Docker containers terminated with exit code 143 | |
| Observations | Tried to access Seafile service, returned 502 Bad Gateway. Called sudo docker ps -a, which reflected Exited (143) 40 hours ago (Saturday 6.30am), for all running Docker containers. Cause of failure suggested to be a SIGTERM sent. Logs for Jellyfin indicated [22:32:39] [INF] [2] Main: Received a SIGTERM signal, shutting down. Going to logs for docker daemon using journalctl -u docker, reproduced below. See full journalctl logs. |
|---|---|
| Cause | Google search for "systemd stops docker" yielded this answer - seems like this occurred universally 8 months ago on 1 Dec 2020. An unattended upgrade forced the Docker.io service to restart. See the following bug report. |
| Fix | Fixed in docker.io commit 20.10.7, should not occur again (see below for detailed flow of events). Alternative is to install docker-ce instead. |

Checked changelogs for docker.io package for Focal 20.04.
As per original bug report on 1 Dec (above), systemd sending SIGTERM was resolved in 19.03.13.
docker.io (19.03.13-0ubuntu4) hirsute; urgency=medium
* d/p/do_not_bind_docker_to_containerd.patch: Update docker.io to not
stop when containerd is upgraded, by using Wants= rather than BindTo=.
(LP: #1870514)
* d/rules: Fix docker.io to not restart its service during package
upgrades, to prevent service downtime from automatic updates via
unattended-upgrade.
(LP: #1906364)
-- Bryce Harrington <bryce@canonical.com> Fri, 04 Dec 2020 23:02:49 +0000
Previous version of docker.io on server is 20.10.2-0ubuntu1~20.04.2, which is backported from 20.10.2-0ubuntu1 (hirsute) (found by searching journalctl | grep commit). New package update below, likely triggered a package upgrade since the update was filed under focal-security. Fixes regression due to dh_systemd_start deprecation.

docker.io (20.10.7-0ubuntu1) impish; urgency=medium
* New upstream release.
- Among new features and bug fixes, the CVE-2021-21284 and CVE-2021-21285
were addressed.
* d/watch: adjust regex to correctly match the tarball files.
* d/rules: make some improvements.
- Adjust regex in the build-manpages target due to some upstream changes.
- Separately install the systemd service and socket.
- Tell dh_installsystemd to not stop the service during the upgrade.
The previous implementation worked fine until debhelper compat 10 where
dh_systemd_start was still a thing. In compat 11, it was deprecated
which means that piece of code was not called.

| NUC unable to connect to network after reboot | |
| Observations | Ethernet port of NUC only has an irregularly flashing green LED, while amber LED is not switched on. Observed on two occasions to occur around the 1-2 hour mark after rebooting the server (sudo reboot and via physical button). During this state, the server does not connect to the local network. After reboot and connecting to a HDMI output, a basic Gnome-based GUI is displayed - only Settings can be opened, built-in Byobu Terminal present but cannot be opened. |
|---|---|
| Cause | Unknown |
| Fix | Installed the ubuntu-desktop-minimal using tasksel install ubuntu-desktop-minimal. Unexpected errors appeared for atom and terminal, both ignored. Disconnected HDMI and keyboard after loading the desktop interface during reboot. Server so far still operational. |
