Gateway-mvc stops responding after ~3 hours of deployment; threads in TIMED_WAITING, no downstream service calls #3841
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.
