--- Comment #4 from Alex Bowers <alex@shopblocks.com> ---
We have ran strace, and the pid's do not appear to match up.

The command we start the server with is:

strace -ff -o /var/log/strace_apache.log -r apache2ctl start

and to reload the server we run:

strace -ff -o /var/log/strace_apache.log -r apache2ctl graceful

We get an a series of files like this:

-rw-r--r--  1 root      root      5895 Apr 18 12:47 strace_apache.log.7791
-rw-r--r--  1 root      root      6449 Apr 18 12:46 strace_apache.log.7792
-rw-r--r--  1 root      root   3337877 Apr 18 12:46 strace_apache.log.7793
-rw-r--r--  1 root      root   3338203 Apr 18 12:47 strace_apache.log.7794
-rw-r--r--  1 root      root      5895 Apr 18 12:47 strace_apache.log.7841
-rw-r--r--  1 root      root      6449 Apr 18 12:47 strace_apache.log.7842
-rw-r--r--  1 root      root   3348810 Apr 18 12:47 strace_apache.log.7843
-rw-r--r--  1 root      root   3346468 Apr 18 12:47 strace_apache.log.7844
-rw-r--r--  1 root      root      5895 Apr 18 12:47 strace_apache.log.7863
-rw-r--r--  1 root      root      6449 Apr 18 12:47 strace_apache.log.7864
-rw-r--r--  1 root      root   3346488 Apr 18 12:47 strace_apache.log.7865
-rw-r--r--  1 root      root   3346357 Apr 18 12:47 strace_apache.log.7866

But our pid for the segmentation fault:

[Mon Apr 18 12:47:35.214485 2016] [mpm_prefork:notice] [pid 7601] AH00171:

doesn't appear to line up at all.

Any insight as to which strace file we hould be uploading?

Providing all seems counter-productive.
