Got too many open files error while performing load test

Wowza Streaming Engine

Hello Support,

i am trying to use wowza load test tool to perform performance load testing to my Wowza Media Server.

I used livestream with 1000 max connection. When it reach around 950 open connection, i got the following exception “too many open files”.

Could you advise whether there is any specific configuration to be done to fix this issue?
