We have several GemFire clients that maintain a local cache and register interest in all keys from a server region:
<gfe:client-region id="myRegion" data-policy="NORMAL"
This has been working well but one day last week, one of the client caches missed a number of updates. We couldn't see anything in the server or client logs to indicate a problem. This client application was restarted that night and has been getting it's updates ever since.
I'm struggling with how to debug this type of problem. Is there something in the statistics that would give a clue as to what happened? I have a feeling there isn't much that can be done to look back and see what happened, but maybe there's some sort of a trace or event listener that could catch a future occurrance?
Any suggestions?
