Issue playing back multiple RTMP live streams

Server:
Linux CentOS 6.(x)
NGINX with RTMP module enabled (compiled myself using an online tutorial)
I use FFmpeg to stream to this server, and one stream works perfectly.
Example of perfectly working stream from IP camera:
ffmpeg -loglevel verbose -rtsp_transport tcp -i rtsp://admin:admin@[ip cam
address]:554/channel1 -c copy -f flv rtmp://[nginx server]:1935/live/test1
and to pull the stream, I use VLC/FFplay, and rtmp url is like so:
ffplay rtmp://[nginx server]:1935/live/test1
Problem comes when I try to stream two streams simultaneously, like so:
ffmpeg -loglevel verbose -rtsp_transport tcp -i rtsp://admin:admin@[ip cam
address]:554/channel1 -c copy -f flv rtmp://[nginx server]:1935/live/test1
ffmpeg -loglevel verbose -rtsp_transport tcp -i rtsp://admin:admin@[ip cam
address]:554/channel1 -c copy -f flv rtmp://[nginx server]:1935/live/test2
in this case, both streams is mostly choppy, and sometimes one stream fails
to load at all.
If I extend this to 10 inputs like so:
ffmpeg -loglevel verbose -rtsp_transport tcp -i rtsp://admin:admin@[ip cam
address]:554/channel1 -c copy -f flv rtmp://[nginx server]:1935/live/test1
ffmpeg -loglevel verbose -rtsp_transport tcp -i rtsp://admin:admin@[ip cam
address]:554/channel1 -c copy -f flv rtmp://[nginx server]:1935/live/test2
ffmpeg -loglevel verbose -rtsp_transport tcp -i rtsp://admin:admin@[ip cam
address]:554/channel1 -c copy -f flv rtmp://[nginx server]:1935/live/test3
ffmpeg -loglevel verbose -rtsp_transport tcp -i rtsp://admin:admin@[ip cam
address]:554/channel1 -c copy -f flv rtmp://[nginx server]:1935/live/test4
ffmpeg -loglevel verbose -rtsp_transport tcp -i rtsp://admin:admin@[ip cam
address]:554/channel1 -c copy -f flv rtmp://[nginx server]:1935/live/test5
ffmpeg -loglevel verbose -rtsp_transport tcp -i rtsp://admin:admin@[ip cam
address]:554/channel1 -c copy -f flv rtmp://[nginx server]:1935/live/test6
ffmpeg -loglevel verbose -rtsp_transport tcp -i rtsp://admin:admin@[ip cam
address]:554/channel1 -c copy -f flv rtmp://[nginx server]:1935/live/test7
ffmpeg -loglevel verbose -rtsp_transport tcp -i rtsp://admin:admin@[ip cam
address]:554/channel1 -c copy -f flv rtmp://[nginx server]:1935/live/test8
ffmpeg -loglevel verbose -rtsp_transport tcp -i rtsp://admin:admin@[ip cam
address]:554/channel1 -c copy -f flv rtmp://[nginx server]:1935/live/test9
ffmpeg -loglevel verbose -rtsp_transport tcp -i rtsp://admin:admin@[ip cam
address]:554/channel1 -c copy -f flv rtmp://[nginx server]:1935/live/test10
Then although I can see all console are streaming perfectly fine, like so:
ffmpeg -loglevel verbose -rtsp_transport tcp -i rtsp://admin:admin@[ip cam
address]:554/channel1 -c copy -f flv rtmp://[nginx server]:1935/live/test10

Can anyone tell why multiple RTMP streams are not being entertained? Is
there any streaming restriction on nginx I am unaware of?
