dovecot - Nov 2006 - Is "Resource temporarily unavailable" an old problem?

Hello,

this might be an old problem indeed, but to really get some help from
Timo and others in the know, they will need the dovecot version:

 dovecot --version

should do the trick.

Regards,

Christian

Hi.

I've installed dovecot recently in a Fedora 5 Linux. It seemed to be OK
but I begun to get the message  "Can't connect to auth server at
default:
Resource temporarily unavailable". When I get the message, dovecot hangs.

The problem is that "temporarily" is not quite true since the only way
to
get dovecot running again is to restart it. As a matter of fact, I cannot
say that it never recovers. What I know is that it is out for a long, long
time.

Then a new problem arose: the time between hang-ups begun to diminish.
Trying to find why I discovered that the number or dovecot-auth processes
was too high (last time I got 169 processes, a lot of them <defuncts>). It
seems that, if I kill all these processes, it takes more time before it
hangs again.

I looked up for messages in the Internet and I found a mail exchange
between people from this list. The first hint I got was to upgrade
dovecot.

As I said, I'm using Fedora 5 and the version distributed with it
was dovecot-1.0-0.beta2.7.i386. I upgraded it to
dovecot-1.0-0.beta8.2.fc5.i386. I couldn't make any direct relantionship
between this versions and the ones in dovecot site so I cannot tell what
dovecot version I'm using in terms of dovecot site versioning.

Any help is welcome.

Thanks,

Ricardo

Well, this is your problem. I guess you're using PAM? So it sounds like
you're using some PAM plugin which hangs and causes Dovecot to break.

beta8 is half a year old, and I've done several fixes since then.
Upgrading might help, but I think it's a problem with your PAM
configuration anyway.
