RE: CPU LOAD

Ok,
Did what you sugested, so i just deleted ALL messages in
postfix queue:
"postsuper -d ALL"

Have a lmtpd process with 100% cpu usage, and it still with
the same usage,
going to restart dbmail and tomorrow morning I'll see if
there's any
diference.

And I'm not a psychic. Like Marc said: check your postfix
queue. There
should also be postfix errors in your syslog. Then, on your
postfix
server run 'mailq' and see if there are certain messages
that have been
hanging around in the queue for too long with errors coming
back from
your own lmtp server. Then, once you establish a postfix
queue-ID,
retrieve such a message from the queue using 'postcat -q
queue-ID'.

make any sense?

Empty the queue?? No angry customers?

As soon as a message messes a lmtp daemon up (although
dbmail should  
work around this) it keeps on using 100% cpu.
Just try killing the daemon which is eating cpu, and see if
the  
problem returns.

Marc, i already emptyed the queue :P
No problem, they were spam messages in fact, there were
about 80 messages
there.

Aaron, now everything is working OK after emptyed the
postfix queue, let
past a few days to see if this returns and I'll contact the
list again for
you guys catch this problem.
Even this been spam messages shouldn't happen as you know.

If strace shows nothing, it likely means we're in a loop
without any
syscalls. If you can pinpoint a message that causes lmtpd to
explode,
that'd be awesome, we can run under gdb and see where the
problem could be
caught.

It is indeed a very tight loop, without any syscalls. We
currently  
have no message saved which triggers this
problem.

Paul/Aaron,
I have an possible idea on what was causing this high load
on lmtpd.
I've noticed some messages that were beeing sent to a user
who has the 
mailbox full.
It's just a remote idea for now, i'll tell you more when i
have something 
more consistent.

I say this because now i had clamd using the cpu too, and i
went to see the 
postfix queue, and most of the emails are some of those,
with the mailbox 
status full

Yap, i've remembered that after reading these last emails...

If this happens again, and I hope so to kiss this bug, I'll
do it.

You should have saved all the messages from the queue and
then for
example by deleting them one by one and restaring
dbmail-lmtpd between
each delete determine which message was the problematic one
that caused
the problem.

Try this or something similar next time this problem
occurs.
