Hi,
since upgrading to Dovecot 2.3.7 I get the following new errors:
2019-07-15 09:10:52 mail dovecot: imap(paul at
iwascoding.com)<32484><goWh8rKNSNZfqJ9R>: Error: file_lock_free():
Unexpectedly failed to retry locking
/var/spool/mail/iwascoding/paul/mdbox/mailboxes/INBOX/dbox-Mails/dovecot-vsize.lock:
fcntl(/var/spool/mail/iwascoding/paul/mdbox/mailboxes/INBOX/dbox-Mails/dovecot-vsize.lock,
write-lock, F_SETLK) locking failed: No such file or directory
It seems that this is related to moving or deleting mails (IMAP). The file at
least sometimes exists, the folder exists. You find my doveconf below.
Thanks,
Paul

The lock fd is already open. Locking is not supposed to fail this way. Also I can't think of any recent changes that could be related to this. v2.2.36 already had the same locking code.

Did you upgrade your kernel as well?It was 2.3.6. But you are true, this seems to be an issue related to AppArmor (in complain mode) that I enabled a day earlier. Have to investigate why AppArmor is given me this?!
