I had that EXACT problem. I do not know the cause. 1.) Email Server 2.) Qpopper, Sendmail, the normal crap for a email server ;-) 3.) 2 times a day, or more, the server would be unresponsive.
Only solution I found, was a hard reboot. I can -not- track this problem down, after going crazy over it, I moved my lusers back over to my 4.2-STABLE machine.
