Something like: ``` ... int bucketId = PartitionedRegionHelper.getHashKey((EntryOperation) droppedEvent); boolean isPrimary = prQ.getRegionAdvisor().getBucketAdvisor(bucketId).isPrimary(); if (isPrimary) { long shadowKey = droppedEvent.getTailKey(); ParallelGatewaySenderQueue pgsq = (ParallelGatewaySenderQueue) cpgsq.getQueueByBucket(bucketId); pgsq.addRemovedEvent(prQ, bucketId, shadowKey); this.sender.getStatistics().incEventsDroppedDueToPrimarySenderNotRunning(); ... `` I didn't try this, but it seems like it should work. I'm not sure if the same idea would work for SerialGatewaySenderEventProcessor.sendBatchDestroyOperationForDroppedEvent since it has a different implementation. btw - sendQueueRemovalMesssageForDroppedEvent has an extra 's'. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
