is a way to limit the amount of memory or processes that it uses?

I had the same problem here. 67M a process eats up the ram quickly.

the --maxchildren=x option to limit how many processes it will spawn:
exec /usr/bin/spamd --max-children=5 -x -u vpopmail -s stderr 2>&1

Go to your run file for spamd (/var/qmail/supervise/spamd/run) and add

After trying what you described and going as low as 2, It seems that
spamd still spawns many sa-learn jobs regardless of that setting.  I
still have to rename sa-learn, at least until I get more RAM.

Warren,

# sa-learn -u vpopmail --force-expire
# chown vpopmail:vchkpw /home/vpopmail/.spamassassin/bayes_toks

you run it?

How are you running sa-learn? Are you talking about the autolearn option? Perhaps your bayes journal hasn't sync'd in a while (or ever). Try running and see if that doesn't speed things up. What does this sa-learn report when

You know I only half read your original email Warren. I thought you had meant that the spamd process was bogging your machine down as emails came in. How are you running sa-learn? Is it in the mailfilter script? Sorry about that!

...so I sent out all of these great replies, but after I had changed my connection and forgotten to change my spf record to match - duh. Anyway, I turned off sa-learn in the mailfilter script and do not have to deal with it now. I am going to pick up another 2GB of RAM (man is ECC Registered RAM expensive!) and then give it another shot.

It's always the little things; like periods in BIND..... ;)

Try changing the line to use the --no-sync option, then run a sa-learn --sync sometime in the evening when the server load is low. I've found that the sync'ing takes a LONG time and eats a lot of RAM if you've got a good size Bayes.
