> I was doing some fault injection testing of 3.2.1 with ZOOKEEPER-508 patch 
> applied and noticed that after some time the ensemble failed to re-elect a 
> leader.
> See the attached log files - 5 member ensemble. typically 5 is the leader
> Notice that after 16:23:50,525 no quorum is formed, even after 20 minutes 
> elapses w/no quorum
> environment:
> I was doing fault injection testing using aspectj. The faults are injected 
> into socketchannel read/write, I throw exceptions randomly at a 1/200 ratio 
> (rand.nextFloat() <= .005 => throw IOException
> You can see when a fault is injected in the log via:
> 2009-08-19 16:57:09,568 - INFO  [Thread-74:readrequestfailsintermitten...@38] 
> - READPACKET FORCED FAIL
> vs a read/write that didn't force fail:
> 2009-08-19 16:57:09,568 - INFO  [Thread-74:readrequestfailsintermitten...@41] 
> - READPACKET OK
> otw standard code/config (straight fle quorum with 5 members)
> also see the attached jstack trace. this is for one of the servers. Notice in 
> particular that the number of sendworkers != the number of recv workers.
