Several reboot and errors after update

[giuseppe96]

Hi everyone,
I’ve done the update to version 11 STABLE but is seems to be all but not stable!
The server now reboot itself often (never happened before) and the web ui crashes everytime!
How can i solve? Should i downgrade to the previous version?

Thanks.

Hardware specs? Which build version (from System -> Information)?
