Locking Errors

[List]

We recently upgraded to version 2.2.10-8 on Centos 7 (from 2.2.10-7) and immediately started experiencing errors in the log file that look like this:

Error: Broken file /mail/user/Maildir/dovecot-uidlist line 891: Invalid data:
Error: Timeout (180s) while waiting for lock for transaction log file /mail/user/Maildir/dovecot.index.log
Error: /mail/user/Maildir/.Trash/dovecot-uidlist: next_uid was lowered (421 -> 419, hdr=418)
Error: Corrupted index cache file /mail/user/Maildir/dovecot.index.cache: invalid record size
Error: Broken file /mail/user/Maildir/.Trash/dovecot-uidlist line 156: Invalid data:
Error: Corrupted index cache file /mail/user/Maildir/dovecot.index.cache: invalid record size
Error: Index /mail/user/Maildir/dovecot.index: Lost log for seq=2 offset=2392
Error: fcntl(write-lock) locking failed for file /mail/user/Maildir/dovecot.index.log: Stale file handle

We are not sure what might be causing this, can anyone help illuminate what’s going on?
