Hi,
Yes kill -Term works for me even without patch of code.
I have one more doubt, I checked with ipcs command that there is only entry
of semaphore and no entry in shared memory.
If I have nothing in shared memory then why am I using semaphore?
What are the critical section in apache for which i

Well, you don't let httpd cleanup anything before exiting by doing
this (it's simply killed immediately).
Why kill with no arg (i.e. kill -TERM) wouldn't be enough?

Hi
I build httpd by myself from source code on HPE nonstop.

Hi,
I tried with the patch of code you have asked for prefork.c and worker.c.
But If I am closing apache gracefully then semaphore is not in shared
location but if I am killing process then still semaphore is there in
shared location.
Is there any way I get rid of semaphore because I want to run s
Hi Yann,

As Luca said,
Hi Luca,
If I choose to go with MPM and to spawn single process then it will create
parent process and then child process where parent process monitor the
server and child process serve the request. But I need only one process
which works for both as parent and child which is achieved in httpd -X.
Hi Hemant,
as indicated in https://httpd.apache.org/docs/2.4/mod/core.html#mutex you
can use different kind of mutex implementations and experiment with them.

Hi Yann,
For my product I need to run apache as single process. As httpd -X works
for me. But the issue is to stop httpd -X, we need to kill process. While
killing the process, semaphore exists in kernel directory.
If I repeat for 10-15 times, then it will give error like no space
available on dev

Hi,
Semaphore is used in multi process environment to share resources within
processes. But when I am starting apache in debug mode i:e single process
then still it creates semaphore. May I know the reason why it is creating
semaphore in debug mode also.
Thanks
