Re: Apache Fork Errors - Found on Windows Server 2019
I just tried the new packages (using the previous build method, with no circular dependency), and it appears that everything is working properly again.

Make sure that there are no Cygwin processes running and that the _autorebase postinstall script completes successfully. (You can check /var/log/setup.log.full for rebase messages.)

Notice how _all_ images are mapped to the same (extremely low) address even though they seem to be rebased properly as evidenced by their address in the parent process.

Re: Apache Fork Errors - Found on Windows Server 2019
> Apache had/has two run modes, pre-forking and threaded. It appears you're running it in pre-forking mode. Try running it in threaded mode. This might be controlled by httpd.conf or some other Apache config file. That is doable, but changing it makes it so that PHP no longer works. To make that change, you just comment out the mpm_prefork.so line and uncomment the mpm_worker.so line to change the mode in httpd.conf: #LoadModule mpm_prefork_module modules/mod_mpm_prefork.so LoadModule mpm_worker_module modules/mod_mpm_worker.so But then, PHP no longer works, so that doesn't really help in this situation, as I must have PHP working. I believe the pre-forking mode used to work previously.
