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.
