SiegeTest:socket error unable to connect - mysql

Question

Really need help to figure out what is going wrong.
Application Background: It is a nodejs with socket.io application.
I am testing my site load using siege windows 3.0.5 tool.
70 concurrent users with 10 seconds
siege -c70 -t10s http://localhost:8082
and getting below error messages.
[error] socket: unable to connect sock.c:230: Address family not supported by protocol [error] socket: unable to connect sock.c:230: No such file or directory [error] socket: unable to connect sock.c:230: No such file or directory [error] socket: unable to connect sock.c:230: No such file or directory [error] socket: unable to connect sock.c:230: No such file or directory [error] socket: unable to connect sock.c:230: No such file or directory [error] socket: unable to connect sock.c:230: No such file or directory HTTP/1.1 200 8.96 secs: 3415 bytes ==> GET / HTTP/1.1 200 8.96 secs: 3415 bytes ==> GET / HTTP/1.1 200 8.96 secs: 3415 bytes ==> GET / HTTP/1.1 200 8.96 secs: 3415 bytes ==> GET / HTTP/1.1 200 8.96 secs: 3415 bytes ==> GET / HTTP/1.1 200 8.98 secs: 3415 bytes ==> GET / HTTP/1.1 200 8.98 secs: 3415 bytes ==> GET / HTTP/1.1 200 8.98 secs: 3415 bytes ==> GET /
it works fine, if I use
siege -c60 -t50s http://localhost:8082
Does this means I can only serve 60 concurrent users. What are above errors messages and how to resolve them.
I am already using connectionPool concept for mysql module and releasing connection after using it.
db.getConnection(function(err,connection)
{
if(!err)
{
connection.query(query,function(err,rows){
connection.release();
if(err) {
throw err;
} else {
callback("null",{rows : rows,tablename : ticker});
}
});
}
});
