Deployed my app under resin to make sure it wasn't a
tomcat issue and get the same error:

I've disabled the firewall on all servers involved and
even tried setting it to one server to make sure it
wasn't just the distributed code.
I also can't seem to get the searchbean to work under
Sun Java on fedora linux when the index is around
50mill.. having to use IBM jdk. Going to try rolling
my own kernel with some higher ulimits for users or
run it as root and see if that gets around the bugs.
