Stephen,
I've seen similar issues resolved by disabling disk caching on the PN
Client itself.
Kind regards,
Jeremy

AM
Please respond to

Richard,
Thanks for the idea.
The part I am trying to understand is why the problem happens with Citrix
but not straight WTS.
If it were a code/cache issue, I would expect it to happen with both
environments. The JRE was not installed in the Windows add/remove sense.
We just dropped the proper JRE on the filesystem, exec'd the 1.5.0 javaws
and away we went (so no change user /[install/execute]). The jnlp was
spec'd to perform an eager download so all files would be downloaded to the
terminal server before application execution. We also "primed" the
environment by performing the application download first.
So, I don't think concurrent access to the cache (though that is an issue
we have to engineer for in production) is contributing to this issue.
Calling Citrix now...
Regards,
Stephen
