Another piece of evidence: once the loop begins, a couple of java
processes start to really use up resources on the remote service's
computer. 

Changing the scope from "Request" to "Application" didn't have any
positive effect.

example, have you configured a small number of sessions?  Are you re-using SOAPHTTPConnection
instances on the client?  Those are what maintain session information.  If your client is
ignoring the session cookie it gets, your server is creating a session for each invocation
(unless you are using a nightly build and have set the option in your deployment descriptor
to not create a session for a request).
