Trying to understand why Websocket connections drop during high concurrency load tests on our BYOC Edge setup. Using JMeter with 200 threads hitting the media server in ap-southeast-1. Getting immediate 1006 close codes after 10 seconds. JMeter config uses standard WebSocket samplers with keep-alive. No CPU spikes on the Edge node. Is there a specific connection limit for BYOC media servers that I am missing?
