PHP 8 CLI hangs sporadically in Windows

I have some PHP processes that run using the CLI through Windows scheduled tasks. Sometimes, and this is entirely inconsistent, the process just hangs and I can see it just sit in Task Manager and it doesn’t go away unless I kill it. This is not process specific, I have multiple different scripts that I run and it happens with different ones (though they do use the same bootstrapping logic). I got a dump file of the processes that hang and analyzed using WinDbg, this is the output:

Followup:     MachineOwner

So it appears it exits PHP upon calling zend_reset_lc_ctype_locale and at that point it’s in ucrtbase, which is at the Windows level.

I’m running PHP 8.1.6 and also tested running on PHP 8.1.24, got the same result.

UPDATE: adding some requested command output from WinDbg

As already mentioned by you this is not an PHP than more an Windows issue.

The ucrtbase.dll is part of the c++ redistributables. You could try to fix it by going to: Control Panel -> programs and features.

Then select all c++ redistributables: Right click -> modify -> repair

This should do the job. Good luck.

Windows just isn’t great environment for php development or hosting.
You could use wsl2 or docker to avoid ongoing environment issues.
