We just replaced our old qmail-scanner + spamd system with a fresh install, and we had a concurrency incoming of about 150. The old single processor PIII 800 handled this just fine.
The new dual PIII 1Ghz would supposedly work much better. With qmail-scanner 1.20 and spamd 2.60 it managed to run out of memory and lockup the machine. I set use_bayes and use_pyzor to 0 because I'm not too sure how to set that up properly with qmail-scanner. Is there a known problem with spamd 2.60 that is causing it to consume 100% of the processor? We process as many as 8000 to 10000 messages per hour. -jeff > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] Behalf Of Dan > Bongert > Sent: Tuesday, November 25, 2003 1:46 PM > To: [EMAIL PROTECTED] > Subject: [SAtalk] Spamassassin hogging 100% CPU time > > > We just rolled out SpamAssassin 2.60 as a spam filtering option to our > users (after using it on IT staff guinea pigs for about a month), and only > have about 20 people using it so far out of a possible 800 or so. > In theory, > the mail server (dual 1.13 PIIIs, 1Gb RAM, FreeBSD 4.8-STABLE) > should be able > to handle the load just fine (it currently delivers about 25000 > messages a day > via sendmail and procmail (didn't blink for the SoBig virus rush), and > probably runs about a tenth of that through SA). > > However, in the last two weeks, I've had SA go haywire, and take > up mucho CPU > time.
