After upgrading from -beta29?

 

Please open a separate bug report for this.

First thing to try: boot in 'safe mode' - possibly an incompatibility with one of your plugins.

upgrading from latest stable to 29, it's happening on 30 also. i'll try disabling plugins

[Unraid OS version 6.9.0-beta30 available]

i've got an issue with sshfs segfaults after i upgraded, bringing down docker containers etc. restarting brings the user shares back.

 

after upgrade to beta 30 getting even more right after a restart
