Again, fixable by not sharing the disk the guest uses with the disk the host needs to load programs from... The disk head is always going to be in the wrong place. But, odds are that the source of the problem is starting too many mail delivery programs, especially if they, or the user's local procmail, starts a spamassassin instance per message. Look at the mail logs for a problem time to see if you had a flurry of messages coming in. Sendmail/MimeDefang is fairly good at queuing the input and controlling the processes running at once but even with that you may have to throttle the concurrent sendmail processes. -- Les Mikesell lesmikesell at gmail.com
