When my server reach ~2000 CCU, Wowza service down (failed to access to port 80,8086). I've no idea about this, because the resource is free enough (bandwidth ~ 2G/5G, CPU ~20%, RAM 10G/32G).
I'm using version 3.5.2 (the lastest) trial edition.
Any help would be greatly appreciated.
The problem suggests more a socket limit. Make sure ulimit socket option is set to a number, not unlimited, say 40000. I would also recommend getting the load test tool, from your posts you seem to be doing a live service ?
