Description
after deploying the gateway service, it works fine initially. However, after approximately 3 hours, it stops forwarding requests to downstream services. The gateway itself continues to respond to endpoint calls, but no traffic reaches the downstream services, even though they are live and healthy.
Observed Behavior:
Gateway responds to incoming requests.
No calls are made to downstream services.
All threads in the gateway go into TIMED_WAITING state.
No errors or exceptions are logged.
Downstream services are confirmed to be up and running.

Research direction
Start with the Gateway-mvc deployment and reproduce the failure after the reported interval, then inspect the gateway's thread state when requests stop reaching downstream services. Confirm the gateway still answers endpoint calls while all threads are in TIMED_WAITING and no errors are logged; done means identifying the cause and restoring downstream forwarding.
