Server keeps crashing randomly

[kratosmike]

Hi everyone,

I keep having an issue that my server keeps crashing 1-3 times a day and I cannot find out why this is happening. The syslog doesn't tell me anything useful, neither does the diagnostics. The pc stays on but just freezes. The web url cannot be opened, the docker applications are unresponsive and SSH is not working when this happens.

 

I really hope someone will be able to help me with this issue!

 

Just one small detail. I accidently discovered that the timezone is wrong, so i did change it from canada to EU\AMS so you might see a jump in time from 13:xx to 22:XX. Sorry!

 

kind regards,

Mike

The syslog in the diagnostics is the RAM copy and only shows what happened since the reboot.   It could be worth enabling the syslog server to get a log that survives a reboot so we can see what happened prior to the reboot. The mirror to flash option is the easiest to set up, but if you are worried about excessive wear on the flash drive you can put your server’s address into the Remote Server field.

Hi I tried this, but unfortunately there is nothing logged to the syslog file prior to the crash, nor the syslog-previous file. Is there nothing interesting in the diagnostics? If you want I can still provide the syslog file?

kind regards, 

Mike

I think I found the issue, or atleast the possible problem. Everytime the server crashes it is a the time that plex starts its maintenance and does its magic. The plex docker also grabs a ton of memory and cpu from what i can see from netdata. I am doing some reading to other related plex issues as well

Yes, the problem was the Plex Docker container, not only from Plex themselves but also from Linux server and Binhex. There seems to be some memory leak that grabs all the memory within seconds, after the Plex maintenance starts or when someone streams a large movie. The solution for me that is working perfectly is by putting Plex in a VM on Ubuntu and passing through the GPU + using Unraid mount tags.

 

In short any Plex Docker causes my system Minis Forum NAB9 to crash.
