Hi Merry Christmas everyone!

 

My server has been unresponsive ~15-30mins after reboot.

After a fresh reboot, I am able to access it from browser and I can pause the parity check due to unclean shutdown.

 

After dockers are started, the server runs fine without issues but it becomes unresponsive through browser or Putty after a while.

Attached is the diagnostics I was able to download before it became unresponsive.

 

Any help is much appreciated!

Update: I pause all dockers and server would become unresponsive a couple minutes later.

Just seconds before it becomes unresponsive I saw the read on Cache drive and flash drive read spiked and CPU increases.

 

I was able to see the processes through putty for a minute or so, but unable to get diagnostics. See attached.

 

There are multiple proccesses of: 

/usr/bin/dockerd -p /var/run/dockerd.pid --log-opt max-size=50m --log-opt max-file=1 --log-level=fatal --storage-driver=btrfs

 

 

 

Enable the syslog server and post that after a crash.

Please see the syslog files attached. syslog

The syslog stopped logging after it froze, I kept the server running until 20:17:00 but the last line in the log was recorded 19:20:44.

 

I was able to boot and stay online when I disabled docker from settings. It seemed to be stable after I manually enable dockers. Initially it stalled for 30mins and it was okay after that, I was able to backup appdata, update dockers, etc.

 

However, upon restarting the server as a test (with dockers enabled), I end up with the same issue. Unraid would freeze after 15-30minutes.

There appears to be a container constantly restarting, see if you can find out which one by looking at their uptimes.

Apologies for the late response. 

I was unable to determine which container was causing problem by looking at the uptime.

 

In a fresh boot, the server would freeze about 15-30mins after it boots when docker is enabled. If I wait for about an hour, it may become responsive again. Just moments before it becomes unresponsive, I can see CPU 100%, that the read on cache drive over 100mb/s and USB flash drive over 20mb/s. The UPS also shows the server is under load as the wattage increase from ~100W idle to ~160W under load. If I let it run for an hour or so, sometimes it becomes responsive.

 

Please see the syslog attached.

 

Dec 28, 2024

13:30 Unraid became unresponsive and load increases to 100%.

Approx 14:30 it becomes responsive

 

14:40, I restarted server with docker disabled

Pause Parity check

After Unraid starts, I manually enable docker and stop all containers.

14:53 Unraid became unresponsive and load increases to 100%.

 

Approx 15:30 I see htop CPU usage died down to 10% and I had to restart Nginx manually.

“/etc/rc.d/rc.nginx restart”

5 minutes later, I was able to access Unraid’s webUI

 

So far, the only method I am able to use my server is to work is to boot with docker disabled, then enable docker and stop all containers immediately, then wait 20-30mins while it hangs, if it becomes responsive I can start all my containers and Unraid has been stable for 12 days until today.

 

 

Jan 9, 2025

I found out Unraid has become unresponsive again at 12pm noon. I sometimes can access webui if I wait long enough (30-60min) with web browser refreshing, but the dashboard, main,etc remains unresponsive.

 

After waiting for ~2.5 hours, it became responsive again and there was a cache disk SMART message “Current pending ecc cnt returned to normal value”.

I was able to download diagnostics after it become responsive, please see the attached.

 

It does not seem like any particular container is causing the freezing issue as it freezes with docker disabled with fresh boot. Also, unraid was stable between Dec29 to Jan8th with the usual containers running. It became unresponsive on Jan 9 and I did not make any changes to it the day before.

 

Your help is much appreciated!
