Customer problem description:
------------------------------

One of our divisions makes an XML integration product that integrates with
our application server. It's got a servlet interface into the main engine of their product (called xCommerce).

When we hit this server with a load of HTTP requests (10 - 50
simulated users), the server leaks memory like crazy (about 1MB /
minute with 10 users). The memory usage of Silverserver.exe(java)
as reported by Windows NT Task Manager grows from 37mb to over
100mb.

This is running:

java version "1.3.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0-C)
Java HotSpot(TM) Client VM (build 1.3.0-C, mixed mode)
java full version "1.3.0-C"

I also see a significant leak in:

java version "1.3.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0-C)
Java HotSpot(TM) Server VM (build 2.0fcs-E, mixed mode)
java full version "1.3.0-C"

All of these are on Windows NT 4.0 SP 6.

If I run -classic on 1.3.0, there is _no_ leak at all. The Memory usage
goes from 37mb to around 48mb and stays at that level.

If I put a System.gc() call into the servlet code so that it does a
GC on each request, we still observe the memory leak.

The death of the server is often an OutOfMemoryError, but I have
received the following from the 1.3.0 Client HotSpot VM:
