dovecot - Aug 2009 - dovecot-auth failed: Not enough space

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Dear all,

I've been trying to get a Dovecot IMAP service running under HP-UX
11.23, IA64. The system has 6GB of spare space under /var and at least
the same amount of RAM free at the current time.

I've compiled from the latest source (1.2.4), using the following options:

# CC="/opt/aCC/bin/aCC" ./configure --prefix=/opt/dovecot
... usual make && make install

My config file follows at the end.

In essence, every time I attempt to start dovecot
(/opt/dovecot/sbin/dovecot, with no options)

I get the following on the command line:
Warning: Last died with error (see error log for more information): Auth
process died too early - shutting down
Info: If you have trouble with authentication failures,
enable auth_debug setting. See http://wiki.dovecot.org/WhyDoesItNotWork

Looking into /var/adm/syslog/mail.log, the lines associated with this
run read:
Aug 24 14:46:25 bilbo dovecot: Dovecot v1.2.4 starting up
Aug 24 14:46:25 bilbo dovecot: Fatal:
execv(/opt/dovecot/libexec/dovecot/dovecot-auth) failed: Not enough space
Aug 24 14:46:25 bilbo dovecot: Fatal: Auth process died too early -
shutting down


I've switched over to using a static passwd file type auth and I still
get the same error.

Hoping someone has some idea why this is happening...
Thanks,
Ashley

Increase auth_process_size or just set it to 0.

Thanks for this Timo. It gets me a little closer!
Now, I start the daemon as before and I get...

# /opt/dovecot/sbin/dovecot
Info: If you have trouble with authentication failures,
enable auth_debug setting. See http://wiki.dovecot.org/WhyDoesItNotWork

Not a good start...

So I poke about in syslog and find...

Aug 24 17:02:37 bilbo dovecot: Dovecot v1.2.4 starting up
Aug 24 17:02:38 bilbo dovecot: Temporary failure in creating login
processes, slowing down for now

Oh no!
Connection via thunderbird client simply stops for the timeout period
and complains that connection to server has timed out.

Processes running on the server are:
# ps -ef | grep dove
    root 26261     1  0 17:14:15 ?         0:00 /opt/dovecot/sbin/dovecot
    root 26263 26261  0 17:14:15 ?         0:00 dovecot-auth -w
    root 26262 26261  0 17:14:15 ?         0:00 dovecot-auth

No IMAP processes at all. :-(

Sorry about the repeated questioning.
A

PS: Yes I do enable auth_debug, but it doesn't tell me anything extra...
