We are using APC with compilation in one of our project, magento version is 188.8.131.52. only FPC extension is installed in it.
At front-end all pages are working fine but Checkout & cart page shows 500 internal server error.
We checked error_log of server. It shows me below errors
(104)Connection reset by peer: mod_fcgid: error reading data from FastCGI server Premature end of script headers:index.php
Is there any way to resolve such issue.
