Patrick Twohig commented on VYSPER-332:
---------------------------------------
I found a comment in the AbstractSessionContext class indicating that the
resource the resource registry doesn't handle the situation where a client
"goes berserk" and could cause a DoS attack. Would that be related?
I also noticed in the BoshHandler that the BoshBackedSessionContext writes a
stanza before finally closing it. I was curious if maybe that write before
closing was inadvertently keeping the session along for much longer than
intended. I traced through the code as best I could, but wasn't able to make
sense of it. My suspicion was that a session is lingering around unable to
deliver messages to a client they just keep stacking up. Thought the
inactivity checker will purge them it seems like it may take longer than
expected. Is that a possibility?
At what point does the BoshBackedSessionContext actually get placed in the
registry?
