Unfortunately, I can't :-(

I've tried producing core dumps, but cannot succeed.

I'm using mpm-prefork, and it seems that no cores will be produced for the child processes, although the master process (the one owned by root) dumps cores on signal 11 perfectly.

Maybe it's because the reproduction scenario involves an apache2 reload (yes, it seems very similar to #694473 : trying to post an edit to a wiki page after an /etc/init.d/apache2 reload has happened).

Are there any more instructions that what's in /usr/share/doc/apache2-mpm-prefork/README.backtrace on how to make sure apache's sub processes can dump cores ?

Thanks in advance.
