Configure httpd.conf with CoreDump to files?

[saosangmo]

I use PHP FPM and in httpd.conf, I add value:
CoreDumpDirectory = /tmp/httpdump

When service httpd hangs, I look in the log /var/log/httpd/error_log:

[core:notice] [pid 21856] AH00051: child pid 22045 exit signal Segmentation fault (11), possible coredump in /tmp/httpdump

But when ls /tmp/httpdump, there is no file.

I miss something?
thanks

Which permissions do you have on your /tmp folder? Can you please post the content of your /etc/fstab file?
If you restart httpd, is there any error in the httpd error_log?

Permission of /tmp folder

[root@csrv01 /]# ls -l
...
drwxrwxrwt. 4 root root 888832 Mar 31 20:33 tmp
....

and the content of fstab:

[root@csrv01 /]# cat /etc/fstab
/dev/mapper/VolGroup-lv_root / ext4 defaults,usrquota,grpquota 1 1
