Description:
------------
When trying to load the opcache with php-scripts from tools and our application in a script to preload the opcache: (here one example line:)
<?php
$bresult=opcache_compile_file('N:\Apache\tcpdf\include\tcpdf_colors.php');
I get multiple entries in the apache error.log file as :
...
[Sun Jun 28 09:58:00.642291 2020] [mpm_winnt:notice] [pid 6572:tid 548] AH00354: Child: Starting 64 worker threads.
VirtualProtect() failed
VirtualProtect() failed
...
This was the first operation (explicitly and manually called from a browser) after a fresh start from Apache/php as a service.
It seems that 2 entries per compile request are generated (without timestamp).
There are no errors reported in php_err.log.
The scripts have been successfully loaded into opcache as reported by
https://github.com/amnuts/opcache-gui - version 2.5.4
The same preload script has been used under 7.x.y until 7.4.7 for a long time without this issue.
Environment:
- Windows server 2019 64bit Standard in a VM under HyperV
- Apache 2.43 64bit from apachelounge
- php 8 alpha1 64bit thread safe from php.net QA download
- php loaded as a module with php_module
Test script:
---------------
<?php
$bresult=opcache_compile_file('N:\Apache\tcpdf\include\tcpdf_colors.php');
Expected result:
----------------
No error log entry in error.log
