WampServer

Hi,

I installed the latest version of Wampserver on to a newly deployed Windows 2019 server (Amazon) including all runtime packages (also downloaded from wampserver) but when I try to run some scripts (php), Apache httpd service is crashing with this error:

Faulting application name: httpd.exe, version: 2.4.62.0, time stamp: 0x66d81b2d
Faulting module name: VCRUNTIME140.dll, version: 14.42.34433.0, time stamp: 0x98c03cc5
Exception code: 0xc0000005
Fault offset: 0x0000000000011504
Faulting process id: 0xd48
Faulting application start time: 0x01db76ef31fd56d7
Faulting application path: D:\wamp64\bin\apache\apache2.4.62.1\bin\httpd.exe
Faulting module path: C:\Windows\SYSTEM32\VCRUNTIME140.dll
Report Id: e043a631-70b1-4471-a899-9d308404de85
Faulting package full name:
Faulting package-relative application ID:

It's crashing a bit randomly, it does not matter which php scripts I run, sometimes it runs fine (50%), but it fails many times.

I also did the same installation on a Windows 2022 server (also on Amazon), but I get the same error.

Any idea what's causing this ...?

Thanks,
Jos.

Hi,

- Go to VisualCppRedist AIO All Releases
Download the latest version of VisualCppRedist_AIO_x86_x64.exe and run it as administrator. All necessary redistributable VC++ files will be installed and any excess or obsolete files will be removed. To ensure that everything runs smoothly, you'll need to disable certain applications when prompted to do so by the VC++ Redist installer.

You can upgrade to Apache 2.4.63.

Hi,
Thanks for your response.
But that's what I did to install the runtime libraries. I downloaded VisualCppRedist_AIO_X86_x64.exe and executed it as Administrator. Apache started crashing .... I went to the Microsoft download site and I even downloaded and installed a more recent version but that one did not resolve the issue either, Apache is still crashing.

I just downloaded the latest one and ran it with Administrator privileges, but that doesn't help, Apache still crashing with same error.

> Windows 2019 server (Amazon)
> Windows 2022 server (also on Amazon)

What does "Amazon" mean? Because that's what all the crashes have in common!

Check the Apache and PHP log files to see if there might be a more explanatory error label.

AWS = Amazon Web Services, it's a cloud host provider.
See: [aws.amazon.com]

Wampserver is designed to run locally, not in the cloud!

I don't think that it really matters....
it's a (virtual) server on a hosting provider.
But it's ok, if you don't know what's causing Wampserver to crash ...

In httpd.conf, you can try increasing the :
- ThreadStackSize normally to 8388608 bytes (8M)
Please note that the value must be given in bytes.

- ThreadPerChild whose default value, under Windows, is 64
Note that the value of ThreadPerChild is limited to that of ThreadLimit, which defaults to 1920.

ThreadPerChild and ThreadLimit are not included in Apache 2.4.62 but are present in Apache 2.4.63, but you can add these two directives - if not already present - just after ThreadStackSize.

I finally found the root cause :-)
it's an incomplete definition in http.conf that is causing this.
Make sure it's complete and looks like this:

LoadModule fcgid_module modules/mod_fcgid.so
<IfModule fcgid_module>
FcgidMaxProcessesPerClass 300
FcgidConnectTimeout 10
FcgidProcessLifeTime 0
FcgidMaxRequestsPerProcess 0
FcgidMinProcessesPerClass 0
FcgidFixPathinfo 0
FcgidZombieScanInterval 20
FcgidMaxRequestLen 536870912
FcgidIOTimeout 120
FcgidTimeScore 3
FcgidPassHeader Authorization
Define PHPROOT ${INSTALL_DIR}/bin/php/php
Define FCGIPHPVERSION 8.1.31
FcgidInitialEnv PHPRC \${PHPROOT}\${FCGIPHPVERSION}
<Files ~ "\.php$">
Options +Indexes +Includes +FollowSymLinks +MultiViews +ExecCGI
AddHandler fcgid-script .php
FcgidWrapper "\${PHPROOT}\${FCGIPHPVERSION}/php-cgi.exe" .php
</Files>
</IfModule>

The section starting with "Define FCGIPHPVERSION ..." (make sure to add the correct PHP version here) needs to be in there. If not, it'll cause Apache to crash randomly with the message that you see in post 1.

Sharing it here in case someone else would have the same issue on Windows Server 2019 or 2022.

Thanks Otomatic, I know it's not always easy to help out on the many different setups that are used everywhere so, I do appreciate that there's someone like you still trying to help out.

Hi,

By doing this, you force PHP 8.1.31 FCGI mode on all local sites (VirtualHost) and all aliases that aren't already in FCGI mode, and this makes a "merry mess", as we say in my house, of everything that was running with PHP as an Apache module.

For example, the localhost page running under Apache module PHP 8.4.4 ends up under PHP 8.1.31 (phpinfo) with a php.ini with errors like :

*** ERROR *** The PHP configuration loaded file is: e:/wamp64/bin/php/php8.1.31/php.ini - should be: E:/wamp64/bin/apache/apache2.4.63.1/bin/php.ini or e:/wamp64/bin/php/php8.4.4/phpforapache.ini

and PHP errors

That's indeed true :-), but I;m not using PHP 8.4.4, I'm only using 8.1.31.
