Strange behaviour

[nico@ccc.uba.ar (Nicolas Baumgarten)]

Hello,
I'm running ZMailer scheduler (2.99.25)
on a SparcStation 20/61 with Solaris 2.4.
Sometimes the load average begins to grow up being the scheduler the main
consumer.
Checking the log files we noticed that the smtp log files grow rapidly
(500 Mb in 24 hours).
If we restart the scheduler the problem stops for a couple of hours.
We usually have about 60 mails in the queue and deliver ~7000 mails per
day.

Any ideas?

Thanks.

allways different, sometimes only one, or from different MX
destinations)
