Hi All,
When we were running spamd V2.43 on our Solaris 8 computer, we found
that the '-m' flag made spamd very unstable. The program would crash
frequently so that no spamd would be running and no filtering was done.
Does anyone know if the "-m" flag is now more stable? We've since upgraded
to Spamassassin 2.54 and Solaris 9.
Or maybe you folks can help me find another solution to my e-mail problems.
It seems that every month or so, our e-mail server goes into swapping hell.
Basically it runs out of real memory and starts swapping. We've
already setup limits on our sendmail so that we have a
CONNECTION_RATE_THROTTLE of 3 and a MAX_DAEMON_CHILDREN of 20. Normally,
spamd takes about 30 seconds to complete, but when it's in swapping-hell
it takes approximately 550 seconds, and since each one takes 20MB of memory,
quite a few (up to MAX_DAEMON_CHILDREN, I suppose) can start up and our
mail server runs out of memory. Usually other things are going on
with the mail server at these times, so it's not entirely spamc/spamd that
is causing the swapping.
I see that there is a "-t" flag for spamc, but this doesn't subsequently
kill the spamd processes after the timeout value is reached. Is there
anyway of telling spamd to stop working if we are swapping a lot? I see
that spamd has a lot of little timeout variables for various specific
tests, but is there an overall timeout for the entire spamd session?
Another alternative that I can't quite figure out how to impliment is
to setup the procmailrc file to check the memory and only run spamc/spamd
if there is enough. We already use procmail to deliver local
e-mail. Does anyone know a procmailrc rule that we can put in that
can check the amount of swapping that is currently taking place?
My current site-wide procmailrc looks like this:
DROPPRIVS=yes
:0fw
| spamc
Thanks,
Cheryl
