Then seriously, reinstall that server with a 64 bit OS. I haven't
heard of anyone thats been running 32bit Varnish in production for the
last two years and having it run stable. The CC-people did for some
time but I believe they migrated due some issues.

If you can't do that, reduce the number of threads to an absolute
minimum, reduce the cache to max 1G, and reduce the stack size until
it's stable.
