while(true)
{
try{ DBClientConnection c;
c.connect("localhost");
c.query();
}
catch ()
{}
}
如果一直循环执行连接，会连接异常，提示：connect invalid socket errno:24 Too many open files terminate called after throwing an instance of 'mongo::ConnectException' what(): Can't connect couldn't connect to server localhost:27017
