>             Project: Geode
>          Issue Type: Bug
>            Reporter: Xiaojian Zhou
>            Priority: Major

> In scenario like:
> {code:java}
> 03:33:03.644 dataStoregemfire4_4494 recovered from disk
> 03:33:03.732 dataStoregemfire4_4494 closing
> 03:33:03.735 dataStoregemfire4_4494 Initialization of region replicate_5 completed, send newId(let’s name it 4494) to gemfire2
> 03:33:03.754 dataStoregemfire2_4493 recovered from disk
> 03:33:03.770 dataStoregemfire2_4493 closing
> 03:33:03.792 dataStoregemfire2_4493 Initialization of region replicate_5 completed. send newId(let’s name is 4493) to gemfire4, but gemfire4 is offline. So gemfire4 does not know gemfire2’s newId 4493.
> 03:34:11.247 gemfire4_9779 restarted, it does not know 4493
> 03:34:11.269 gemfire2_9856 restarted, it sends oldId=4493, newId=9856 to gemfire4, but gemfire4 does not know either of gemfire2’s oldId and newId
> When gemfire2_9856 asked gemfire4_9779 for its state, gemfire4_9779 replied "I don't know you", then gemfire2_9856's starting ends with ConflictingPersistentDataException.
> {code}
> We need more log to identify the issue.
