Hi Ken,
         I have not see it again.  I am wondering if it was an issue 
of not having swap.  It happened last weekend when some level 0 dumps 
over nfs are run, so its possible too much demand on memory and 'bad 
things' started to happen. I have since enabled swap and no issues 
since.  On another box which has a similar mix of spamd,clamav, 
sendmail, no issues at all.
