Chris Conroy commented on ZOOKEEPER-1043:
-----------------------------------------
We are seeing this fairly regularly on 3.4.6. Luckily we haven't seen it in
production yet. However, this does appear to be fairly common for our developer
environments (osx).
This bug is still marked unresolved (and unassigned). I don't see any mention
of this bug in ZOOKEEPER-1504 and it too is marked unresolved. What is the real
current status of this issue?
