Connection Reset. Some please help me!

Randomly i get a message on the console saying...

2011-10-09 12:15:50 [INFO] Connection reset

No errors or anything pops up besides that! Sometimes nothing happens to the server, BUT other times people stop being able to connect. Its almost as if the server crashed I dont know what this means and i was hoping someone here will and help me out. Here is some info about my server.

What Have You tried already- I have no idea what it means, but i did only try to get a automatic restart plugin. But it failed.

Ok i solved it.
The problem was caused by Permissions 3.1.6
