Slowly delivery

Hello,

Our mailserver has got very slow since yesterday.
It's taking about 10 minutes to delivery a simple
message to any user on the own local server.

Looking for something thing weird, I found some
messages executing pflogsumm...

It's showing several messages like this
in the section RCPT of message reject detail:
452 Insufficient system storage; from=<souzarubenig.com.br> to=<ivanmelim.com.br>

More many message like this:

Master daemon messages
----------------------
      3 daemon started
      1 terminating on signal 15

Here we have two mail server, one of them (smtp.melim.com.br)
to do only smtp relay and the other one (mail.melim.com.br) also
does smtp relay (not so used) and it's a pop server where
messages are stored.

Both of them has DJB dnscache and postfix-1.1.11 running on, and the
mail.melim.com.br also has amavisd-new-20020517 installed.

I know that is may be a amavis issue, but, it's working
fine this way a long time and I have any idea what can
be taking so many time from the MTA.

May be just two process from amavis listening be so little
but, what does it have working fine for so long?

Ok, my main doubt is:
Does anyone can give any idea about what can make my
MTA wait so many time to delivery the messages?

PS: I found nothing wrong on maillog file.

Thank's
Ronan
