> Did you check what Dimitry suggested?

in /etc/xinetd.conf file, the default number in the "instances"
line was 60. As you see, I've changed it to 200. I'll see the results
tonight, now I'm just watching the server and restarting as needed.

I really hope this will work. I'll write the results.
I don't want anyone to have some trouble like I have now.

Thank you very much Daniel and Dmitry
