I&#39;m not sure about that..<div>Can you try increasing that number?. That&#39;s the exact wiki that I&#39;ve saw. and increasing from 1000 to 1500 stop showing that problems. Probably is a problem related with the time that is taking to close the sockets.</div>

I remember looking at the Mina documentation to see how to fix it, but something should be wrong there.. because it&#39;s not supposed to open a huge amount of sockets for working.</div>
