Getting httpd to dump core on RHEL5

[Graham Leggett]

Hi all,

I am trying to get a core dump out of an RHEL5 system, and I am 
struggling to do so.


Following the instructions at 
http://httpd.apache.org/dev/debugging.html#crashes, I have set ulimit 
-c unlimited, and I set CoreDumpDirectory to /tmp, but with no luck.


Is there some further magic that needs to be done to get httpd to dump 
core successfully on Linux?


Regards,
Graham

On our Ubuntu boxen having ulimit -c unlimited in the httpd startup 
script and CoreDumpDirectory /tmp in httpd.conf is sufficient.


kill -SEGV some-httpd-pid should yield a coredump IIRC.

The coredump will be useless unless you have compiled with -g though, 
but I guess you already knew that ;)
