> Similar to GEODE-1885...In this case the issue is with update and with both offheap and non-offheap regions.
> During transaction operation, if there is concurrent redundant bucket re-balance is in progress, the client can miss update event, if its primary queue is hosted on the node where bucket gets moved from.
> Consider, three node cluster N1, N2 and N3. With:
>     Client C1 connected to node N2.
>     Primary bucket region B1 on N1. And secondary bucket for B1 on N2.
>     A Transaction is started on N2, which updates an entry on B1.
>     When the TX is committed. At the same time the Bucket B1 on N2 is moved to N3.
>     The Tx commit message from N1 is sent to N2. This also includes the subscription message, satisfying the client C1.
>     On N2, for offheap region, when bucket is not found locally, the exception response is sent to back to N1 without processing the subscription message.
> How to reproduce:
> Add following tests/lines in ClientServerTransactionDUnitTest:
>   public void testUpdateSubscriptionEventsWithOffheapPrWhileBucketRegionIsDestroyed() {   testSubscriptionEventsWithOffheapPrWhenBucketRegionIsDestroyed(forop.UPDATE);
>   }
>   public void testUpdateSubscriptionEventsWithPrWhileBucketRegionIsDestroyed() {
>     testSubscriptionEventsWhenBucketRegionIsDestroyed(false, forop.UPDATE);
>   }
