[6.10.3] Kernel panic?/crash all system, webui not reachble - unstable

You should try to set your 'Docker custom network type' to IPVLAN in Settings / Docker (advanced setting).

Thanks @ChatNoir i change from mcvlan to ipvlan and after some time, 5-8h the webUI was not reacheble, smb was not reachable but dockers was reachable. I try to SSH from the router(he is the gataway/same VLAN) directly to the Unraid and have connection. I did diagnostics. The problem is appeared for first time when i update from 6.9.2 to 6.10.1 after this i have constantly problems with Unraid, before the update uptime was 90+days aways. Now not more than 2-3 days. Diagnostics attached, when the server was unrachable and only SSH access was accesable. After the reboot, server is not reachable again only SSH from the same VLAN.

JFYI I have LAG + VLANS with working config since 6.9.2 without updates/changes. (to be sure i disable all drop/reject rules and write accept rule from this network where is the server, no difference).

EDIT: After long time of search the root problem, memtest, cpu stress and etc, i switched from docker .img to folder(i want to recreate all from beginning) and all problems disappear. Weird..

after this downgrade to 6.9.2 but sometime the server just was unreachable and only manual restart do the thing.

If the server now also crashes with v6.9.2, a previous known good release with it, it suggests something changed or there could be a hardware problem, enable the syslog server and post that after a crash to see if it catches something.
