Strange thing because exactely the same thing happened to me: I found my mail server agonizing this morning, OOM-killing everything as its 512M RAM + 512M swap were exhausted ... I just had to killall spamc spamd to recover it. Apparently there may be a kind of spam/virus/forged mail which is geared toward killing spamassassin. > Tips for performance tuning SA : > 1) use the spamc/spamd combination -- it stresses the system a > lot less > > 2) Limit SA to scan only a few messages concurrently.

The only problem I see is that my mailserver receives lots of mails; this may force it to lag behind too much. > 3) Don't scan really large messages, or scan just a subset of them > (btw, the default for spamc is to not send messages larger > than 250k to spamd; you can adjust this with the "-s" option > or by conditions on the director in exim.conf) > > | But obviously, I would rather have a virus scanner take care of > | those large MS-virus-attachments, so SA won't have to deal with > | those. > > Naturally, but I would just use a version 4 ACL or the system filter > (I believe the system filter will be run before the director that runs > SA, the filter can "fail" (bounce) or "seen finish" (drop) the > message) > > | I hope this could reduce the load somewhat in situations like > | this.

You shouldn't be running anything older than that. I'm using the 2.20 version that came with woody. I tried installing the version from unstable, but it complained about some unsatifiabled dependencies (can't remember which by now). Spamassassin seems to be a package needing frequent upgrades to counter spam evolution. Is there a mean to upgrade woody's sanely ?
