I peeped into apache log file I get

[Wed Jan 19 17:26:41 2011] [debug] mod_deflate.c(615): [client ip] Zlib: Compressed 632 to 385 : URL /index.php

Do you have any idea about it ?

Premature end of script headers

This message means the PHP script died before outputing any content-type to apache. If you have ob_* functions activated it could be any error on your PHP script, or a timeout, check your set-time-limit parameter in PHP for timeouts.

Check as well that your exception handling output the correct content type if you want to output an error message.

To check all parameters that can have an impact you must check the timeout parameters and the size limits ones. Here are some of them:

Apache:

  • LimitRequestBody

PHP:

  • post_max_size
  • upload_max_filesize
  • max_input_time
  • max_execution_time
  • and maybe memory_limit as well
