I've been calling this the Email Scud problem. I've been hoping for a patriot missle for a long time. I have noticed the same problem with v2.63 and v2.64. I upgraded to v3.0 hoping that the problem would go away but it's still there.
It's happened to me about 3 times, where an email will be sent to my server that specifically causes the problem. Killing the spamd process causes the sending MTA to resend. It usually occurs with an email with a large MIME attachment. In the last occurrence, the attachment was around 20MB and was only a .TXT attachment. The sending MTA will resend its Scud missle and I'll see the 250MB spamd process using up all available CPU. Unfortunately, I didn't save the problem message and its attachment. Hopefully, that sheds a bit of light on this common problem. jae -----Original Message----- From: Morris Jones [mailto:[EMAIL PROTECTED] Sent: Saturday, October 02, 2004 11:44 AM To: users@spamassassin.apache.org Subject: Memory usage spikes ... Yesterday I commented that I was seeing spamd children eating a lot of memory, pushing the machine into swap. I've been keeping an eye on the spamd children this morning. Overnight, all five children were using around 4 meg. This morning sometime, one spamd child shot up to 250M: Mem: 513948K av, 504660K used, 9288K free, 0K shrd, 15532K buff Swap: 1052216K av, 263780K used, 788436K free 68408K cached PID PPID USER SIZE STAT %CPU %MEM COMMAND 1537 15624 root 250M S 0.0 44.5 spamd child 25394 15624 root 40056 S 0.0 6.1 spamd child 1432 15624 root 38932 S 0.0 6.0 spamd child 1241 15624 root 38768 S 0.0 6.0 spamd child 1754 15624 root 39308 S 0.0 6.0 spamd child Yesterday afternoon when I killed and restarted spamd, they were all using about that much.
