Chuck,

I will see if I can get access - the machine is more or less a black box for
me I'm afraid, and on an internal network that I cannot access directly.
Maybe I can setup something on a box inside the net that they can use. I
will see what's possible, thanks for the suggestion

True

The mapping for this one is very static, one very specific url.  As are most
of the others. Main servlet grabs /** and passes to a binary servlet for
binaries. The only direct jsp's are for the 404 and 500 errors, all others
get forwarded from one of the servlets.

True, clutching at straws there I think ;)

I added a secondary mapping before starting, which will of course mean the
same servlet gets called and not prove a lot. I will try to get some
monitoring window to the server so I can grab some more info on the state of
the servlet and the vm at the time it occurs.

A hanging servlet would mean timeouts for the client I think? Or error 500?
