Description

When several gateway receivers have the same value for hostname-for-senders (for example when running Geode under kubernetes and a load balancer balances the load among the remote servers), it has been observed that number of connections in GW senders pool used for sending ping message is much greater then number of dispatcher threads, although in this case only one connection could be used (since destinations have same address and port ).
