[Dovecot] Is "Resource temporarily unavailable" an old problem?

[Ricardo Dias Campos]

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
