FWIW we also see this under OpenVMS.  We had this happening intermittently
back in the Fall of 2000 and it went away, then it came back this month with
a vengence.  We ran from Nov 2000 to Dec 2001 without a re-boot and have been
rebooting every 2 weeks or less since, for unrelated reasons.  Earlier this
month the Web stalls started... the application (Purveyor) keeps creating
new tasks which do nothing until it runs out of the 20 available slots.
From then on, it's dead until it's restarted.  I was also guessing this was
a resource problem but have no idea what.  I finally noticed that the stalls
all seem to occur right after a single one of our 640 lists is being
accessed, always from the same domain: stonesoft.com.  The list is public
and I don't see any stonesoft.com subscibers, but the early morning stalls
during extended sessions suggest they are caused by something routine.
It's an unremarkable list, maybe even smaller than most in terms of archive
size and traffic.  I'm still looking into it.
