Anybody have trouble with Reports Server hanging?

Anybody have trouble with Reports Server hanging?

My environment:
9ias (9.0.2.1.0) Patch 2705870 was installed recently,
Windows 2k (App. Server and Infrastructure on different boxes),
Both physical boxes are production quality hardware,
9i Compiled Forms & Reports,
Some Reports are accepting passed parameters,
we have tried running the reports with DESTYPE=pdf and DESTYPE=html.

Reports are hanging in the Reports Server. The only way we can remedy this is by re-starting the Reports Server Service from Windows everytime!
When we do, the first report always runs (regardless of what report it is). However, the second one hangs most of the time. Again, we cannot associate any one report as responsible for failing.

I am wondering if any other people have run into this problem?

Thanks,
Todd
