Topic: Apache 2.4.20 500 error

[sailor]

Overnight the website went on vacation and started giving out 500 errors instead of the default page.

Right now the only thing I see is in the event log from a couple days ago:

Faulting application name: httpd.exe, version: 2.4.20.0, time stamp: 0x57039cd6
Faulting module name: ntdll.dll, version: 6.1.7601.23418, time stamp: 0x5708a857
Exception code: 0xc0000005
Fault offset: 0x000000000004eef1
Faulting process id: 0x21a8
Faulting application start time: 0x01d1baf8bd501d58
Faulting application path: D:\Apache24\bin\httpd.exe
Faulting module path: C:\Windows\SYSTEM32\ntdll.dll
Report Id: a8c322c8-2a1e-11e6-9770-0050569003f8

This is Windows 2008R2 SP1.

I had a couple other previously, but it seemed like it kept running ok

There's nothing in the error log (the error log is not there actually for today). i just restarted the service and it's up and running ok now.

Also, found some php error that it was trying to allocate 1.7 gigs of memory. Using php 7.0.5 _64 for Wordpress. There is a newer version of php with some memory fixes, so will try that.

Did you remove the memory limit in your php.ini? it should be possible by default to have such a huge memory usage.

if you have a high frequency of visitors you should use php over mod_fcgid. that keeps apache free from phps memory usage.
