---------------------------------------

Hi [~nnag] ,

When serial gateways senders are stopped and one server is restarted, then the restarted server is stuck at the startup, indicating the following:
{code:java}
[info 2022/06/13 11:37:22.550 CEST server-ln-3 <main> tid=0x1] Region /ny.0_SERIAL_GATEWAY_SENDER_QUEUE has potentially stale data. It is waiting for another member to recover the latest data.{code}
Before this fix was introduced, the server would normally start with a running serial gateway sender. Did you intentionally change this design base behavior?

> In the commit for GEODE-7458, when the sender is stopped, the region backing the queues are no more closed, but just remove the cache listeners.
> This is causing a problem, as the regions continue to exist, it keeps on storing entry events and hence the queue size never gets to zero.
> Also, as the region exists but before attaching the cache listener when restarting the sender leads to entries being never removed from the unprocessed event map.
>  
> As mention in the PR for GEODE-7458 - "This option is only applicable for Gateway Senders with enabled persistence."
> Hence believe that it is ok to close the region as the disk files will still be maintained. so when we restart the values can be obtained back from the disk stores.
