> "Fatal Error Cannot create mutex"
Great error message. It should at least contain the error code,
to be able to diagnose the problem.
Anyhow, if both sites run under the same user account (and both
use impersonation or not), that shouldn't cause CreateMutex() to
fail. But still it is likely a good idea not to share the OPcache
instance in your case. I'm not sure that changing
opcache.cache_id to PHP_INI_PERDIR is sensible, but it shouldn't
be necessary for IIS anyway, because you can run the two sites
with different application pools, and you can use pool specific
environment variables to run with different cache_ids.

Description:
------------
I have a Windows Service (PHP 7.4 CLI), plus two IIS web sites, configured to run under the same
Windows User ID with network privileges, because they need to access a certain network share.
One web site was using PHP 7.3, and one web site PHP 7.4 (because it's a development/staging
site).
In the 7.4 php.ini "cache_id" is set.
When I attempt to run the first web site also under 7.4, then scripts will start failing, due to
"Fatal Error Cannot create mutex". I'm assuming, since both IIS sites (with different
application code versions) now share the same PHP version and UserID, this results in a clash?
If so, would the solution be to allow different/unique "cache_id"s to be configured in the
.user.ini of each IIS site, rather than only being able to configure a common one in the system-wide
php.ini?
