Subject [users@httpd] Windows Apache 2.4.9 restarts itself
Date Tue, 24 Jun 2014 13:36:08 GMT
I face the problem, that Apache restarts itself unexpecteldy without
obvious reason.

-> (OS 6)The handle is invalid.  : AH00356: Child: WAIT_FAILED --
shutting down server
-> (OS 10038)An operation was attempted on something that is not a
socket.  : AH00344: accept() failed.

Apache Version:
  * Problem occurs on 2.4.9, both VC10 and VC11 compiled ones
  * Problem does NOT occur on 2.4.4
Operating System:
  * Microsoft Windows Server 2012 Standard

The problem occurs since the Apache upgrade from 2.4.4 to 2.4.9.
At this moment I reverted to 2.4.4 again because the random restarts
cause downtimes.


Relevant configuration settings:
ThreadsPerChild 300
AcceptFilter http none
AcceptFilter https none
EnableSendfile off
EnableMMAP off


Apache works as a caching reverse proxy (mod_cache_disk)


Typical logfile fragment:

[/log]

Have you got any idea, why this can happen?

In the windows eventlog I can't find any relevant entries at the time
that apache restarts.

Please help if you can

Kind Regards
