> On node transition from Master state some in-flight pending configuration 
> change tasks might be attempted to execute after Master transited into 
> Detached/Replica state when node has not been synchronized with new Master or 
> new Master has not been elected yet. On trying to execute configuration 
> change tasks  BDB HA Store can try to create a JE transaction. The creation 
> of JE transaction can hang for a duration of timeout interval which is 
> configured in TimeConsistencyPolicy. The following database write operation 
> would cause ReplicaWriteException and transaction abort. 
> The store should fail immediately in this case rather then pointlessly 
> waiting for some time before failing anyway. More over, a pointless waiting 
> blocks configuration thread making it impossible to perform any other 
> configuration tasks
