We have Windows Server 2012 R2, Apache 2.2.31 and Php 5.6.18, Zend Server Version: 8.5.3
Apache seems to be hanging more and more frequently, a restart of apache seems to fix the problem most times. There are a quite a few php-cgi's open when we look at the the process viewer.
Windows event viewer shows multiple events like this,
18 JUL 2016 09:13:23 Faulting application name: php-cgi.exe, version: 22.214.171.124, time stamp: 0x56b9d4d2 Faulting module name: php5.dll, version: 126.96.36.199, time stamp: 0x56b9d4ce Exception code: 0xc0000005 Fault offset: 0x002f8a02 Faulting process id: 0x1550 Faulting application start time: 0x01d1dfad0acd3f1b Faulting application path: C:\Zend\ZendServer\bin\php-cgi.exe Faulting module path: C:\Zend\ZendServer\bin\php5.dll Report Id: e05b4091-4cc7-11e6-80bb-002590634814 Faulting package full name: Faulting package-relative application ID:
What things can i do to debug this further so I can figure out what is going wrong?
A user reports a similar exception (0xc0000005) on stackoverflow which suggests that the problem is a memory access error, and the code accesses a nil pointer (or is blocked from access for protection reasons..);
Their remedy is to disable the EMET features on the binary exe. There is some information on disabling EMET features for specific applications here;
If you are not running EMET, or that does not fix your problem, there is also a newer version 8.5.5 of Zend server which might include a bugfix;
and newer versions of php since 5.6.18 (current 5.6.22); http://windows.php.net/downloads/releases/archives/
