Mike Drob commented on CURATOR-165:
-----------------------------------
I think this might be the same issue as described in CURATOR-136. [~zhaogang] - is there any chance you can upgrade to 2.7.0 and see if that fixes your problem?

> We use curator for leader election within our 2 clients, sometimes none of the 2 clients was a leader.
> We checked the log and found this caused by a exception which was being throwed in method LeaderLatch.checkLeadership(), after throwing this exception the curator won't do the leader election. Here is error log:
> ERROR org.apache.curator.framework.imps.CuratorFrameworkImpl - Background exception was not retry-able or retry gave up
