While they were running at full CPU I simply set the 'nice' levels to +15 so they wouldn't disrupt other services much while troubleshooting. As far as I know everything kept running fine and no downtime was experienced on any services. I didn't do the kill right away because I wanted to make sure it was some important maintenance task they were doing, or something like that... I couldn't come up with any answers though, so finally I did the deed. After restarting all effected services things were fine and CPU usage has been normal for several hours now. Has anyone experienced anything like this with amavisd-new before?
