Are you _sure_ your other requests aren't relying on something locked by 
this process?

I'd suggest a couple of things:

- there's a product out there called DeadlockDebugger for Zope which can 
help you find out where the other requests are getting stuck

- find some of those new fangled Oracle tools (you know, the ones you 
pay inordinate amounts of money for an that are riddled with critical 
security vulnerabilities ;-) and see if you can figure out what's going 
on from the oracle end of things

good luck!
