I see an error in the log that shows the EMS is not able to connect to port 1113. usually that causes a failure to startup. How are you running the EMS, as a daemon process/service or as a shell application?
In regards to your 700 connections, is that 700 VOD file pulls? So you have done something like:
pullstream uri=rtsp://localhost:5544/vod/myFile.mp4 localstreamname=id1
Have you done the above 700 times, or do you have 700 players (such as VLC) hooked up and playing one or two of your streams?
I’d like to get a better feeling for how you have setup your whole test so that we can identify where the problem lies.
