dovecot - Sep 2010 - Processes remaining

Hi all,

on my system ("AIX 6.1" 64bit) after "doveadm stop" there
are some
processes still alive:

    vmail  3997878        1   0 16:54:26      -  0:00 dovecot/imap
dovenull  4915236        1   0 16:54:26      -  0:00 dovecot/imap-login
     root  6029330        1   0 16:54:20      -  0:00 dovecot/ssl-params
     root  6553702        1   0 16:52:01      -  0:00 dovecot/log
    vmail  6881392        1   0 16:54:21      -  0:00 dovecot/imap
  dovecot  7078140        1   0 16:52:23      -  0:00 dovecot/auth
dovenull  7733396        1   0 16:54:20      -  0:00 dovecot/imap-login
     root  7864502        1   0 16:54:21      -  0:00 dovecot/auth -w
     root  9240650        1   0 16:54:20      -  0:00 dovecot/config
  dovecot 12189718        1   0 16:52:01      -  0:00 dovecot/anvil


After some minutes I can see less than before:

     root  6029330        1   0 16:54:20      -  0:00 dovecot/ssl-params
     root  6553702        1   0 16:52:01      -  0:00 dovecot/log
  dovecot 12189718        1   0 16:52:01      -  0:00 dovecot/anvil

But these seem to be permanent.

Restarting dovecot there is an error sometimes logged:
Sep  9 17:08:17 Buckow local3:err|error dovecot: master: Error: service(auth):
Socket already exists: /var/run/dovecot/auth-login


And - some restarts later:

     root  3997884        1   0 17:07:21      -  0:00 dovecot/ssl-params
     root  6029330        1   0 16:54:20      -  0:00 dovecot/ssl-params
     root  6226004 13172840   0 17:14:04      -  0:00 dovecot/config
     root  6553702        1   0 16:52:01      -  0:00 dovecot/log
  dovecot  6881398        1   0 17:06:13      -  0:00 dovecot/anvil
     root  7733432 13172840   0 17:14:04      -  0:00 dovecot/log
     root  7864522        1   0 17:06:13      -  0:00 dovecot/log
  dovecot  7995430 13172840   0 17:14:04      -  0:00 dovecot/anvil
  dovecot  9240682        1   0 17:11:20      -  0:00 dovecot/anvil
     root  9306298        1   0 17:13:28      -  0:00 dovecot/ssl-params
     root  9371814        1   0 17:11:20      -  0:00 dovecot/log
  dovecot 12189718        1   0 16:52:01      -  0:00 dovecot/anvil
     root 13172840        1   0 17:14:04      -  0:00 /usr/sbin/dovecot

What's wrong?

Do you have shutdown_clients=yes (default)?

If you kill ssl-params, do the other two processes die too?

There's probably some problem with Dovecot detecting that process on the
other side of pipe has died. What does "dovecot --build-options" say?

I think this is a bug in AIX, but I added a workaround for it:
