Henry Robinson commented on ZOOKEEPER-792:
------------------------------------------
Just to update - I've found that zkpython tests are failing in trunk, and I
don't want to commit a patch when the tests are broken. I'll be creating a JIRA
shortly to address the problem once I've looked into it slightly further.

> We recently upgraded zookeeper from 3.2.1 to 3.3.1, now we are seeing less
> client deadlock on session expiration, which is a definite plus!
> Unfortunately we are seeing memory leak that requires our zk clients to be
> restarted every half-day. Valgrind result:
> ==8804== 25 (12 direct, 13 indirect) bytes in 1 blocks are definitely lost in
> loss record 255 of 670
