High load on my server
Hello,
I've some troubles with spamassassin. Sometimes (and i don't know why
exactly) my server has high load (like 50 or 60 or more) so it's
impossible to connect via ssh, everything crash (apache, qmail, vpopmail,
etc...) and i have to go to the datacenter to reboot the server... and if
i'm able to connect via ssh (after having waited 40 minutes...) i can see
that perl or spamd are the processes which take the most part of the load
(perl due to qmailscanner, who invoke spamassassin). I'm under a debian
stable, i've installed spamassassin via package AND source... maybe it's
because of this
In my syslog i've this just before it crashed :

Blocking From Users
Posted by Brent Kennedy <br...@cfl.rr.com>.
Just a quick question. If I add an entry into the configuration file to
block all emails sent from "*@mycompaniesdomain.com", that should block
anyone trying to send emails into my mail server using my companies domain
as a spoof. The question is.. Will this end up quarantining all emails sent
to mycompaniesdomain.com?
I am only using SA to filter incoming emails.
Thanks
-Brent

Unless you've got at least 2GB of RAM in the system, you've got way too
many spamd children running and are swap thrashing. You normally want
to budget at least 45MB of RAM per child in addition to whatever memory
other things on the system need.
So, you can start off by reducing the number of children to avoid load
related problems in the first place (note: spamd is failing due to
system load, the system load is probably due to swap thrashing and not
spamd). Then you can upgrade SpamAssassin to a newer version which has
a better chance of surviving, and not then further contributing to, such
a high load.
