Although we seem to be past them now and are dealing with the issue
of WO not appearing to let go of the memory it uses and it having
"broken pipe" issues.
It is not WO that is not letting go of the memory. It is the Java
JVM. It is a JVM implementation issue, not a WebObjects issue.
The broken pipe is just a symptom of your application taking too long
to process requests, aggravated by not dispatching requests
concurrently. Fix the performance issue and this will go away.

Hello Owen;
its better to explicitly call System.gc() in WO App's. Whats the
rule of thumb here in terms of how often, is there a better spot
than others etc etc ?
It is only ever a hint, never a demand. I have resorted to this
infrequently.
That's correct, but I think the problem arises that if it does
decide to do a full-on garbage collect then it has a tendency to
freeze all of the threads for a bit while it does it. This can
lead to jittery responses from the application.
Are you actually getting "OutOfMemoryException"-s logged?
cheers.
