Do you have a stack trace for the "Exception from service object: null"?  Needless to say,
that would be a big help.

My next question would be, might you be running out of some resource on Tomcat?  For 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).

I am sure there are other possibilities, but sessions are what leaps to mind.
