   @albertogpz, hostname-for-senders is a string value which represents the 
hostname that is given to the senders. This means, that if you start 2 (or more 
servers) on the same machine they can have the same value. Could you create two 
servers with a gateway receiver each, with the same hostname-for-server value 
and see if this solves the problem.
   
   If not, we have to seriously put our heads together and try and come up with 
a solution to the problem. As I'd prefer a test to be in place that reproduce 
the issue and then of course fix it. Might even mean that we might have to 
create a whole new framework to test these kind of issues.

> 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), the ping messages sent from the gateway 
> sender client are only sent to the receiver (endpoint) to which the sender 
> connected first.
> The other receivers will not get the ping message which will imply that the 
> connections towards them will be closed after the configured timeout expires.
> This ticket is a continuation of the work done ticket GEODE-7565.
