Thanks a lot! I found the root cause afte= r diving into code.=A0

The error is caused by my w= rong settings. I try to create a too big scoreboard file (which is even big= ger than my physical memory). The size of the scoreboard file is generated = in=A0ap_calc_scoreboard_size() as follows:

=A0=A0scoreboard_size =3D sizeof(global_score)= ;
=A0=A0scoreboard_size +=3D sizeof(process_score) * server_limit;
=A0=A0scoreboard_size +=3D sizeof(worker_score) * server_limit * thread_limit;=

Then, in open_scoreboard(), it uses mmap() to create the scoreboard f= ile by shared memory which cause the error.


=A0=A0=A0=A0=A0=A0= =A0rv =3D apr_shm_create(&ap_scoreboard_shm, score= board_size, NULL,
=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0= =A0=A0=A0=A0=A0=A0=A0global_pool); /* anonymous shared memory */

=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0= =A0=A0=A0=A0=A0=A0"Unable to create or access scoreboard "=

=A0=A0=A0=A0=A0=A0=A0}

I have to say that the= system response is really important. If the code can check the errno and p= rovide accurate information. User will get less confused.=A0

Thanks again, Martin. I do appreciate your help!!

Hi, all.

I did a hard reboot because of system crash... and my Apache httpd-2.4= .1 cannot start with the following error message:

[Wed Mar 21 00:42:56.034927 2012] [core:crit] [pid 32253:tid 140720646= 657856] (22)Invalid argument: AH00004: Unable to create or access scoreboar= d (anonymous shared memory failure)

It seems that my shared memory is corrupted?=A0

Can anyone tell me how to repair and make apache to work?

Thanks in advance!
