Topic: Apache 2.4.16 Win64 100%-CPU/failing exit threads

[cangoou]

Hello!

I just migrated from PHP 5.6.8 32-Bit/Apache 2.4.10 32-Bit to PHP 5.6.14 64-Bit/Apache 2.4.16 64-Bit on a Windows 7. Everything works fine so far, it feels like it's a bit faster as well. I took the same http.conf and php.ini as before.

The problem: Sometimes (not always) loading a page or image takes "forever", meaning: the site appears after 2 (exactly!) minutes or not at all. The CPU-usage for httpd goes up to 100%. When trying to
net stop apache2.4
it takes very long as well. I looked at the error.log:
[Sat Oct 03 14:15:31.452137 2015] [mpm_winnt:notice] [pid 11076:tid 380] AH00422: Parent: Received shutdown signal -- Shutting down the server.
[Sat Oct 03 14:15:34.336238 2015] [mpm_winnt:notice] [pid 33048:tid 304] AH00363: Child: Terminating 80 threads that failed to exit.
[Sat Oct 03 14:15:34.336238 2015] [mpm_winnt:notice] [pid 33048:tid 304] AH00364: Child: All worker threads have exited.

So there seems to be 80 crashed threads. This never happened before with the 32-bit versions. Any idea what might cause this or how to debug this?

Do you have:

AcceptFilter http none
AcceptFilter https none
EnableSendfile off
EnableMMAP off

?

Ah, didn't know that is necessary. Seems to work now, thanks a lot!

Sorry, it works, this time it was an error of myself...
