Premature end of script error -- tried everything... Any help?

I have searched and tried many solutions and cannot fix this issue. Here is the error:

Code:

[Fri  Dec 02 00:26:43 2011] [warn] [client xxx.xxx.xxx.xxx] (104)Connection  reset by peer: mod_fcgid: error reading data from FastCGI server
[Fri Dec 02 00:26:43 2011] [error] [client xxx.xxx.xxx.xxx] Premature end of script headers: index.php
[Fri Dec 02 00:26:48 2011] [error] mod_fcgid: process  /usr/local/cpanel/cgi-sys/php5(16037) exit(communication error), get  unexpected signal 11

No matter what I do, a 500 server error is thrown on this page. It worked fine 1 week ago and it works fine on the development server. There are no other errors that I can find. If anyone has any hints, please let me know. I am running apache 2.2 and php 5.3.8.

I have tried:

1) Deleting the suphp, suexec, and apache error log

2) Changing php versions

3) Changing handlers (dso, cgi, fastcgi)

4) Enabling and disabling php suexec

5) Disabling and enabling eaccelerator

6) ensuring all folders/files in my web root belong to me

7) no errors in the suexec log

8) no errors in the web root apache log... Only the above errors in the main apache log
