Well, it looks like ICEPush or your app tries to finish Request/Response
processing from the different threads. Normally only one thread may work
with a single Request/Response instance at the same time, and only one
thread has to complete/finish the Request/Response processing.
If you can create a simple testcase, which reproduces the issue - it
would help.

If you don't use Comet and from the stacktraces it looks like you don't
- then there is no need to enable it.
Thanks.
