after migrating m3.4.1 to a new server with (all software x64, todays version)
everything was running fine for several weeks in production.
But: I couldn't upgrade to m 3.5.
Apache crashes, no php errors, no moodle errors, Win Log: error by opcache dll.
I disabled opcache and .... m3.5 upgrades gracefully.
Turning on opcache --> works as expected, alle problems seem to be gone.
There is still a (hidden) snag: site administration --> notification restarts this problems again.
Are there any php commands concerning opcache in this script which were declared depreciated or even removed in 7.2.3?
Should I disable opcache while updating?
Wouldn't be a really smart solution for production.
