Now I use VS17 build for production (httpd-2.4.66-251206-Win64-VS17.zip).


Thanks for the tip, will try that too but they removed the download files, have to grab them from somewhere else...

Can you check instruction support between VS17 and 18 build system?

I found different in my "identical" hardware. More powerfull use i9-9900 CPU, and more slowly config use G5400 Pentium processor.

Pentium does not support AVX2 instruction set, and do not crash with VS18 builds.

Other component is the same.

This is build the same as the VS17 one, now VS18 with no updated dependencies. So with curl 8.17.0 openssl 3.6.0 Jansson 2.14.1 , and build 4.2.bat

So VS18 is the cause.

We do not know how many users are dealing with it. I put a note on the download page and ask users to report

So I'm afraid your statement is not quite true.

What is left that PHP is the cause. No crashes seen with other products.

Is it only PHP 8.5.x ?

You may try :

VS17 with the new curl, jansson and Openssl 3.6.1

Since I’m using PHP with fcgid, shouldn’t the PHP version I use be NTS? I’ve always used the NTS version without any issues. If I downgrade to 2.4.65 and keep the same NTS PHP version, the instabilities disappear.


You can use NTS (non thread safe) because if it crashes it shouldn't bring apache down. The TS = Thread safe version has a few check to make sure it doesn't crash. Those checks take some time.So it is a little slower. But in real world it didn't matter to me with thousands of requests. The TS version runs fine.

For all those people with this problem. Download a clean version from Apache Lounge. Download a fresh version from windows.php.net. Follow the setup of https://www.apachelounge.com/viewtopic.php?t=2394

Then change the port of apache like 8080 and 8443 to run a parallel instance for testing. Or simply use a different machine for your tests.

Nope, not true in this specific case, apache crash/restart no matter if php is ts or not, as module or fcgi.
