Dear Mr. Iulyb, after 4 days of Zeroshell run I don’t have impossible load more. Actually I have 8,5Mb/s, 2361 connections, 6% load. I’m so sorry that I cannot more reproduce the problem. In this time I changed some ftp test server solutions and voip pbx setting. I don’t know if the problem can arrive from something not perfect on their config… I’m so sorry, if I can help you….
Here the picture of the problem.
