At one of our sites, we are running Apache 2.4.34 and php 7.2.12 64 bit Windows. Periodically we are seeing php7ts.dll crashes with exception 0xc0000005. I checked the extensions and they are all the ones delivered with php with the exception of php_sync.dll and php_win32service.dll. Could these be causing the problem? Or is there something else I need to look at?

Thanks in advance for your help

I don't know that extensions, but php extensions for windows used to crash apache in the past.

The 0xc0000005 is access violation. Maybe you can see something about it in the windows event log or apache error log.

It is recommended to save php error and php start up errors in a log (you can set both in php.ini)

Also if apache crashes too often I recommend to use mod_fcgid. That makes apache more stable. You can find that in the how to

if you still have a question please ask again.

Did you download php_win32service.dll from https://pecl.php.net/package/win32service/0.3.0/windows? And php_sync.dll from https://pecl.php.net/package/sync/1.1.1/windows?

If you can pinpoint what is causing the crash, you should file a bug report at https://bugs.php.net/

Anyway: switch to mod_fcgid (and the NTS version), as James is recommending.

I checked the Windows event log, the Apache error log, the PHP error and PHP startup logs, but only found information in the Windows event log. Unfortunately, I can't really correlate the Windows event log error to anything specific.

Yes, I did download the 2 dlls from the sites you mentioned.

James and Jan-E,
Thank you for your responses and information. I will look into using mod_fcgid, though I wish there was a way to isolate the specific problem.
