Its not closing opened ports after its done

[kksharma1618]

Run this command to get opened port

netstat -an | grep -e tcp -e udp | wc -l

Then run load test, eg:

websocket-bench -t primus -p websockets -a 2000 -c 100 -v -w 1 ws://xxx.xxx.xxx.xxx:80

Then again check your open ports using above command (After load test is done completely).
You will find that roughly 2000 ports have been opened and not closed since last run of this command.

If I run load test multiple times I start getting

Primus Worker error{"code":"EADDRNOTAVAIL","errno":"EADDRNOTAVAIL","syscall":"connect","target":{"domain":null,"_events":{},"_maxListeners":10,"_socket":null,"_ultron":null,"_closeReceived":false,"bytesReceived":0,"readyState":3,"supports":{"binary":true},"extensions":null,"_isServer":false,"url":"ws://xxx.xxx.xxx.xxx:80/primus","protocolVersion":13,"binaryType":"arraybuffer","_closeTimer":null}}

Example from my machine:

Launch bench with 2000 total connection, 100 concurent connection
