later this aft, I found the problem ... it seems that running webalizer
against the logs of one of my domains genrated a 'dnscache' file that is
>1gig in size. When webalizer runs, it loads the whole damn thing up into
memory ... before things locked up one of these times, I got to the point
where I could see that swap was something like 800+Meg used and rising
*roll eyes*
