Description

On some systems, the operating system can have intermittent problems resolving hostnames. Sometimes resolutions work. Other times it fails.

This can result in intermittent failure of InetAddress.getByName() when it's called in InternalDistributedMember(ServerLocation location) (constructor). That exception gets re-thrown as a GemFireConfigException. When that exception is thrown, it ends up stopping processing up in GatewaySenderEventRemoteDispatcher.readAcknowledgement().

Event processing should not stop in this case. It should retry so that the system can recover.
