We are using the Standalone Generator since V2.3 form PHP 5.2 until now on 5.6. The problem is after upgrading our server to PHP5.6, Apache 2.4 with FastCGI, the generator runs about 7-8 minutes then throws a Compression Error (In Firefox, Internal Server Error on IE) and stop running.
I configured high time (9000sec) for PHP and FastCGI max execution. The error is the same in Version 7.1 and 6.1. The cron jobs also stops.
Please advise. Thank you.
