Michael Han commented on ZOOKEEPER-3141:
----------------------------------------
The failure does not reproduce in my stress test job which just ran this single
test (https://builds.apache.org/job/Zookeeper_UT_sTRESS/). It can be reproduced
on nightly build on trunk. Likely caused by interference from another test
case.
