Hi,
Thank you for the response!
I looked into child.c, and see that the first line in Error log:
(OS 6)The handle is invalid. : AH00356: Child: WAIT_FAILED --comes from:
shutting down server
child.c Line 1125+: rv = WaitForMultipleObjects(num_events, (HANDLE
*)child_events, FALSE, ……
This is the place that causes the restart.Right... The other code I pointed out is what makes this call different than before.
The second line in the error log:
(OS 10038)An operation was attempted on something that is not acomes from:
socket. : AH00344: accept() failed.
child.c Line 641+: if (context->accept_socket == INVALID_SOCKET)
I guess the second line in the error log is just a consequence of the
server shutting down?I expect so.
no, I can’t build httpd. It would be great if you could provide a
patched version that I could install in _production_ environment.
I can’t reproduce the error on a test server, I can just install the
version on a productive server, and wait for the error to occur. The
error occurs sporadically.
It is essential that the patch included in the build doesn’t break
things (particularly the ability of apache to restart when an error
happens).The Apache Lounge folks would need to run the build for you to ensure that it has any patches you're currently using and that the toolchain is in sync.
Right now I hope to make some permanent changes in the next couple of days to improve diagnostics in this area and commit the changes to httpd trunk. At that point you might be able to get the Apache Lounge folks to roll them into a special build. ???Here are the diagnostic changes I added:Perhaps the Apache Lounge folks can get you a build of 2.4.9 with that in it.
As you found out, I use the apachelounge-build atm.
Thank you for your help!
Kind regards
Maria Imp
