Martin, The message itself looks like the recursion problem... a spammer sent a drug spam, and the rejection message (to a local address) looped some 122 times at 5-second intervals until SA bombed. It's hard to imagine ANY program that can disentangle 122 MIME-encapsulated emails inside each other without running out of resources.
So I would say the problem is not SA; it's an MTA setup that doesn't detect a mail loop after eight or ten times around. The spammer appears to have used a spoofed local envelope sender, which contributed to the problem.

I have tested the message with 'spamassassin' (ie. not spamc/spamd) with the same result. The scanning took 21 CPU seconds on a Intel Pentium 3, 1133 MHz and consumed 180 MB memory. Am I the only one seeing this problem? Could someone else test the message and report if you too are seeing excessive cpu and memory load. The message is at http://www.math.ku.dk/~zuziak/sa/satrigger.txt .
