Mahadev konar updated ZOOKEEPER-597:
------------------------------------
Attachment: ZOOKEEPER-597_4.patch
this patch fixes the 2 latest failuires we saw:
- http://bugs.sun.com/view_bug.do?bug_id=6427854, a bug in the jvm which is
fixed by a selector.open.close() call in a static block in NIOServerCnxn
(thanks ben for the idea)
- the other cancelled key exception is fixed by wrapping sendbuffer with try
catch for exceptions.
i looked for any other calls that can cause commitprocessor to fail in this way
and could not find anything else. hopefully this is the last of such problems.

> ASyncHammerTest is failing intermittently on hudson trunk. There is no clear
> reason why this is happening, but
> it seems from the logs that a session connection to a follower is failing
> during session establishment - the
> failure seems to be a problem either on the follower or leader. The server
> gets the session create request, but
> it stalls in the request processor pipeline. (we see it go in, but we do not
> see it com eout)
> unfortunately all efforts to reproduce this on non-hudson trunk have failed.
> Even trying to reproduce by
> running on hudson host itself (manually) has failed.
> We need to instrument the client session creation code in the test to dump
> the thread stack if the
> session creation fails.
