joshkrz Posted November 10, 2023 Share Posted November 10, 2023 (edited) For the past few months my server keeps crashing and locking up completley every week or so, sometimes more often sometimes less. It requires me to hold the power button to force shutdown, which has eventually led my cache pool to become corrupt. The only two entries shown before the last crash were: Nov 9 19:37:08 home-server monitor: Stop running nchan processes Nov 9 19:37:08 home-server kernel: BUG: Bad rss-counter state mm:00000000084043e9 type:MM_SHMEMPAGES val:1 This issue seems to coincide with me upgrading from 6.11.5 to 6.12.4 but I cannot be 100% sure. I've looked at this thread but as with the OP hugepages seems to be disabled on my system. Thanks! Edit: It also appears this person has the exact same issues as me including a corrupt cache pool, it was also posted around the same time I think my problems started. home-server-diagnostics-20231110-1116.zip syslog-127.0.0.1.log Edited November 10, 2023 by joshkrz typo, added other examples, added logs, clarity Quote Link to comment
Solution joshkrz Posted December 14, 2023 Author Solution Share Posted December 14, 2023 (edited) So after some testing by disabling docker for a couple of weeks I deduced that it was docker that was the issue. I followed the instructuions outlined here: https://docs.unraid.net/unraid-os/release-notes/6.12.4/#fix-for-macvlan-call-traces in the section that allows you to keep macvlan enabled. So far I have had no cashes and my Unraid machine is stable once again. Edited December 14, 2023 by joshkrz 1 Quote Link to comment
hmorrico Posted May 29 Share Posted May 29 Did your issue go away? Have been having the exact same thing happen for the last few weeks. I do use a custom docker network for my qbittorrentvpn setup but I see my docker network settings is set to ipvlan. Should I try macvlan? Quote Link to comment

Yep, my server has been solid ever since but I'm still dealing with the fallout of my cache corruption as a result of these crashes with various permission issues from restoring backups to outright not being able to restore nextcloud or mariadb. Follow the instructions in the link I posted starting with "For those users, we have a new method that reworks networking to avoid issues with macvlan." Quote Link to comment
