I have one problem with OpenVPN. There are a lot drops records in the openvpn log file on the server:

According to "Jan Just Keijser - OpenVPN 2 Cookbook" root of the problem is incorrect config options.see the screenshot
But, as you see, my config has such options. Could you please help me to solve this problem.
