Sijie Guo commented on BOOKKEEPER-79:
-------------------------------------
I have run 'make clean check' against latest trunk (including BOOKKEEPER-114
and BOOKKEEPER-115) for several times. most is OK, sometimes I got following 2
exceptions.
first one is Exception during socket.close, as commented in previous comments.
second one is SERVER_DOWN exception thrown in publish_thread (running more than
~250 seconds) in #testRandomDelivery, which due to hub server disconnect to zk.
I added code in publish thread to catch such exception to avoid it.
