We did the upgrade to 8.0.6 on Proxmox v3, and I see some issues.
For one, the memory is not being consumed like before: The container has 6GB RAM assigned, and is only using about 2GB of it...
Some of the users are complaining about not getting into their mailbox (small mailboxes), getting a 'Loading' splash screen, but not reaching the actual mailbox contents, where my own mailboxes are several GB in size with lots of sub folders and extra connected shared folders, which loads super fast...

Any reason why this behaviour has changed since the upgrade?
Logfiles seem (don't really know where to look for exact issues) fine to me...
