Starting Nov 8, I’ve been seeing fairly consistent segfaults from amavisd. I’m unable to determine what is causing it. Below is a listing of occurances in /var/log/messages. The server has been running fine (normal load – mail traffic is normal). Also I checked uptime (reboot was Nov.1) and recent emerges. The only emerges close Nov.8 was rrdtool and cacti (11/5 and 11/6). I posted this on the Gentoo forums to see if someone can point me in the right direction. I saw mention that this could be related to hardware. I’m hoping this is not the case, especially since it seems to point to perl5.8.8.

I was able to analyze the last segfault (15511) which happened to be a logcheck message to me. Nothing out of the ordinary with that message. It was a plain text message and not too large. I also have the domain whitelisted, so it should have zipped through amavis just fine. Interesting that things improved from Nov 9 to Nov 11? I’ll keep you posted as I find answers.
