Oleg Kalnichevski commented on HTTPASYNC-23:
--------------------------------------------

Kireet,
I do see from the log that the session http-outgoing-6079 gets somehow stuck, 
but there is nothing in the log that might help me understand why. Everything 
looks healthy. I am afraid I would need a reproducer I could run locally, 
preferably with as little custom code as possible.
