April 28, 20242 yr Good day, Got a wierd issue, seem like for 2 morning in a row, I am not able to login to my web interface and the serve need a hard shutdown. I was able to login to the web interface before it crash this morning and notice that 2 cpu core where stuck at 100%. I then try to stop the array but was stuck and not able to stop it. I try to click the reboot button a few time until no longer able to use the web interface. Had to go on the server and force shutdown. Other wierd thing, when the core at 100% and if i run "top" in the command line, noting use my cpu at 100%. What could be the cause of this? How do i get that syslog? And does it reset after a hard restart? Thanks Edited April 28, 20242 yr by patthe
April 28, 20242 yr Dashboard considers I/O wait in it's displays. Next time it happens, reply back with your diagnostics before you reboot
April 29, 20242 yr Author Hi, It happened again. The web interface of the server crash again. On another note, all my other service seem to be working at that time. So this just affect the Unraid Web interface. I connect a keyboard without a screen, lol, guess the user and password and type the diagnostic command and Suprise, was able to get a server diagnostic. Hopefully this help, if not, will activate SSH. server-diagnostics-20240429-0725.zip Edited April 29, 20242 yr by patthe
April 29, 20242 yr Community Expert There are Macvlan related call traces, these will usually end up crashing the server, switching to ipvlan should fix it (Settings -> Docker Settings -> Docker custom network type -> ipvlan (advanced view must be enabled, top right)), then reboot.
April 29, 20242 yr Author Good day, Switch to ipvlan and reboot. Will give it 2 day to see if fix and will update on status. Thanks again!
April 30, 20242 yr Author So this morning, no crash yet, but one of my cou core is stuck at 100%. I attach new diagnostic. On another note, was able to stop all the docker and my cpu came back normal. I may try to turn off docker one by one tomorow if I can to see what docker is causing a problem maybe? server-diagnostics-20240430-0545.zip

May 1, 20242 yr Author Ok update,. Again one of my core this morning was at 100%. I turn off my docker one by one until it goes to normal and figure out it was plex docker. Now why does it eventualy make my unraid web interface crash and how can I prevent this recurring every morning? When I check the cpu usage In Docker, was only using like 3% wierd, but 100 of one core was use on the main unraid page. server-diagnostics-20240501-0545.zip Edited May 1, 20242 yr by patthe
May 1, 20242 yr Check your transcoding setup. It should be something like "/tmp/plex/" and not "/tmp/".
May 1, 20242 yr Author this is what is is currently have : But why the transcoding make it crash every morning? I'm not even using plex at that time ? Edited May 1, 20242 yr by patthe
May 3, 20242 yr Author Solution I think I fix it. I add the Intel GPU TOP plugin and set it up in Plex. I also had to delete the CODEC in plex as I was not able to transcode anything 4K on the fly. Seem to be stable now for the last 3 day. Thanks to all.
