I have had to downgrade once more to 2.4d10 as 2.5c1 was bringing my servers to their knees. Every 48 hours or so the server was reporting i/o errors on many services using TCP/IP ports and Xitami was refusing to run CGI programs and php refusing to shell to external exes. Stopping Xitami and restarting solved the problem each time. Jason Ozin Technica Solutions
