> GEODE-7921 in 1.13 introduced this issue. When processing a message used by 
> entry idle expiration to find out when an entry was last accessed on any 
> member of the cluster it now checks for a null cache, region, and entry. If 
> any of them are null the message simply returns. The problem is that the 
> expiration thread that sent this message waits forever for a reply. So unless 
> the member that found a null leaves the cluster, the expiration thread will 
> be hung waiting for a reply that will never be sent.
> The fix for this is easy. We just need to send a reply of zero when we find a 
> null.
