> Issue Type: Bug
> Components: quorum
> Affects Versions: 3.5.0
> Environment: ubuntu 13.10
> Server environment:java.version=1.7.0_51
> Server environment:java.vendor=Oracle Corporation
> Reporter: Michi Mutsuzaki
> Fix For: 3.5.0

>
> ObserverTest.testObserver fails consistently on my box. It looks like the
> observer (myid:3) calls QuorumPeer.getQuorumVerifier() in a tight loop, and
> the leader (myid:2) is not getting enough CPU time to synchronize with the
> follower and the observer. The test passes if I increase
> ClientBase.CONNECTION_TIMEOUT from 30 seconds to 120 seconds. I'll attach a
> log file.
