sanfark Posted July 17 Share Posted July 17 (edited) This has happened for a few nights now. My room is slightly warm and I am running an old AMD X2 that has does have heat issues when two or more people are streaming plex, or when streaming plex and transferring a large amount of files to Unraid. That being said, why is this 2am 100% cpu happening now? Three nights in the past 7 days. I have checked netdata and it states that the 'nice' process is running at 95%. Having troubles determining what this 'nice' process/dimension is. It's not being very nice. system.softriqs also had a high usage of one dimension at that time, called 'RCU' Network inbound/outbound was minimal, in the 10-15kbps range. Disk reads were a little strange. Oscillating between 0MBps - 4.5MBps I also checked 'plex activity' in the gui and no user attempted to reach the server Application found! Wtf is Media? Also, the user 'nobody' was running at 90% during this time as well, I assume Media is owned by Nobody How do I know what 'Media' did and why?

MAM59 Posted July 17 Share Posted July 17 "nice" is not actually a real command, just a starter shell that modifies the task priority and launches the real job. So you need to find out what process is started from nice. Quote Link to comment

There is a mover, which I don't know what it is or why it's there but the time does not add up. My high CPU started at 2:53 but this scheduler is set for 3:40 Edited July 17 by sanfark .

Veah Posted July 17 Share Posted July 17 If it's happening at the same time daily, that makes me think some sort of scheduled event. If not scheduler, perhaps a script, or something within a docker container or a vm. The big brains may stop and have a look if you get diagnostics attached. They are real good at ciphering all that data quickly. Quote Link to comment
sanfark Posted July 18 Author Share Posted July 18 Well, it happened again last night. Woke me up at 4am with cpu heat alarm going off. I logged onto the server and found Plex was detecting intros to a library! I restarted the plex service to stop it. Not sure why it's doing that every night though. I grabbed the diagnostictower-diagnostics-20240718-0828.zip Hopefully there is something glaring as to why this is occurring. Luckily my CPU heats up so much that the alarm goes off otherwise I never would have known this was happening Quote Link to comment
JorgeB Posted July 18 Share Posted July 18 If the CPU is overheating you need to improve the cooling, if all is working well, the CPU should be able to stay under 100% load 24/7 without overheating. 1 Quote Link to comment
sanfark Posted July 18 Author Share Posted July 18 For sure. I'm actually in the middle of rebuilding the server as I am currently running an AMD Athlon X2 in a somewhat warm room, it can't even handle a large file transfer while streaming a direct stream without crossing the 60 degree alarm, which for some reason, I cannot find where I set it now. I am curious as to why Plex was 'detecting intros' in the middle of the night. This does not seem normal to me and come to think of it, this has happened a year or two ago as well and just stopped.

Mainfrezzer Posted July 18 Share Posted July 18 Im surprised as to why the alarm is set on something so low as 60 degrees Well, usually you do maintenance at night cause, the typical human being tends to sleep at that time and thus does not interrupt any playback that happens during the day. Just disable the shedule in plex and youre good, lol Quote Link to comment

sanfark Posted July 19 Author Share Posted July 19 yea - I might be getting mixed up with the disk temp settings but I could have sworn that this was a problem in the past and I upped the alert to 60 degrees. But again, could have been disk alerts. Sucks troubleshooting this on a headless machine! Quote Link to comment
