> In the PeerToPeerSessionCache, the createOrRetrieveRegion method creates the region when the Tomcat server is started.
> The PeerToPeerSessionCache stores this region in a field called sessionRegion. It also stores the cache in a field called cache, and the fronting region in a field called operatingRegion if local caching is enabled.
> When the DistributedSystem is disconnected, the cache and its regions are closed.
> When the DistributedSystem is reconnected, the cache is recreated but not the regions. This is because they were created using API rather than in XML or cluster configuration. This can be changed by setting use-cluster-configuration=false, but it won't really make a difference.
> Thats because the PeerToPeerSessionCache's references are to the closed cache and regions.
> Adding a ReconnectListener to the PeerToPeerSessionCache so that these references are re-established will address this issue.
