I am seeing a lot of errors since the upgrade, on multiple client 
accounts:

Info: Connection closed: read(size=7902) failed: Connection reset by 
peer (UID FETCH running for 0.242 + waiting input/output for 108.816 
secs, 60 B in + 24780576+8192 B out, state=wait-output)

Using NFS storage (not running with the mail_nfs_index or 
mail_nfs_storage)

Was something changed in terms of IO/Idle timeouts?

Tried doing reindex/resync, but did not help.
