This problem is now affecting more than just that one user. The 2nd (at least) victim is myself, so this problem is now more urgent.
Any thoughts on this? Should I start familiarizing myself with source code, or just downgrade to 2.1.16 again? I hate going backward. :-(
thank you

We just upgraded from 2.1.16 to 2.2.13. One user is experiencing problems when using the shared namespace. Specifically it happens when opening/reading a message and when deleting messages. These functions work for other users. So far, this appears to be only affecting one user.
The shared folder is a local ext4 file system and utilizes acls
