Internal Server Error : error reading data from FastCGI server

[fredrickojackson]

J2.5.14/VM2.0.24/PHP5.2.17 hosted at godaddy.
I am getting "internal server error" at random intervals. In my server logs are error like:
[Sat Nov 02 17:38:18 2013] [11943811] [fcgid:warn] (104)Connection reset by peer: [client 66.249.66.103:41614] mod_fcgid: error reading data from FastCGI server
[Sat Nov 02 17:38:18 2013] [11943811] [core:error] [client 66.249.66.103:41614] End of script output before headers: index.php

I have tried to research this problem to no avail. I have tried various settings in .htaccess . no luck.
If anyone can give me a clue, i'd be grateful.
thanks
Fred
