Hi,
The Dovecot wiki states that Dovecot's master restarts all died
processes, which is good for availability. But when I kill dovecot/auth
(to simulate an error condition which happened on a machine), the
authentication fails with:
Nov 16 14:32:40 be dovecot: imap: Error: net_connect_unix(auth-master)
failed: No such file or directory
It seems -albeit it gets restarted- dovecot/auth doesn't re-create its
socket file.
Before:
# ls /var/run/dovecot/
anvil auth-worker doveadm-server
anvil-auth-penalty config dovecot.conf
auth-client dict empty
auth-login director-admin lmtp
auth-master director-userdb login
auth-userdb dns-client master.pid
# ps auwx | grep dovecot/auth
dovecot 87455 0.0 0.0 20024 3832 ?? S 2:34PM 0:00.01
dovecot/auth
# rm /var/run/dovecot/auth-master; kill 87455
# ps auwx | grep dovecot/auth
dovecot 88815 0.0 0.0 20024 3776 ?? S 2:36PM 0:00.01
dovecot/auth
# ls /var/run/dovecot/
anvil config dovecot.conf
anvil-auth-penalty dict empty
auth-client director-admin lmtp
auth-login director-userdb login
auth-userdb dns-client master.pid
auth-worker doveadm-server
I've deleted the auth-master socket because if I don't, you can't see
that it's not re-created. :)
Is this a normal behaviour? I understand that killing dovecot/auth is
not, but Dovecot could survive this easily, if recreating and re-using
the new socket file would work. And loosing dovecot/auth happens
sometimes (I don't yet now why).
Thanks,
