[AMaViS-user] Time out cause

Hello,

I'm using Amavisd-new+MySQL+Postfix platform.

I saw some message in maillog:

status=deferred (delivery temporarily suspended: conversation with
127.0.0.1[127.0.0.1] timed out while receiving the initial server
greeting)

Moreovere I tried to lauch amavisd-nanny but I get:

# /usr/local/src/amavisd-new-2.5.3/amavisd-nanny
process-id task-id elapsed in elapsed-bar (dots indicate idle)
or state idle or busy
BDB no dbN 1: Unknown locker ID: 4a19cd No such file or directory at
/usr/local/src/amavisd-new-2.5.3/amavisd-nanny line 122.
exited

I have the following 'db' package installed:

# rpm -qa | grep db
dbus-1-0.60-33.2
db-4.3.29-15.2
gdb-6.4-19.10
dbus-1-mono-0.60-33.2
dbus-1-python-0.60-33.2
db-devel-4.3.29-15.2
gdbm-1.8.3-243.2
db-utils-4.3.29-15.2
dbus-1-glib-0.60-33.2
gdbm-devel-1.8.3-243.2

I can't figure out what it can be the cause as I have the same software
installed on a different macchine and all works fine..

Moreover, could be the two anomalies related?

TIA,

rocsca

Rocsca,

Is postfix trying to open more connections to amavisd
than there are amavisd child processes ($max_servers) running?
Is this a pre-queue filtering setup?

The BerkeleyDB::Hash::new failed, it reported 'Unknown locker ID: 4a19cd'
as a primary error (the 'No such file or directory' might be bogus).

Don't know, could be related if both problems show up at the same
time. If a database would end up in a permanently-locked state, the
'conversation with 127.0.0.1 timed out while receiving the initial
server greeting' could also be a symptom. Amavisd log might be
able to tell more. Trying db 4.4.20 or later might help too.

Yes, I have a pre-queue filtering setup.

I have no idea if Postfix has reached the number of connections equal to
$max_servers.. :-( But I think that this is normally done..

Infact..

OK. I have reloaded amavisd-new and all has continued to works
correctly. It seems a 'one-time' problem. But anyway it coulb be pretty
nice to point the cause. The main disease was that I didn't be aware
that amavisd-new didn't work at all. The postfix active queue has
reached an huge number of messages.

So, now, I have found a way to monitor the status of amavisd-new,
watching the size of Postfix queues and the latency of messages..

Thanks,
