dump_bt not working when trying to analyse apache core dumps

Question

I am trying to use dump_bt to analyse an apache core dump as we are getting segmentation faults after moving servers.

The info I got on how to do it is at the following link:

http://www.omh.cc/blog/2008/mar/6/fixing-apache-segmentation-faults-caused-php/

When I run dump_bt I get undefined command, the link I posted also states a conflicting command bt_dump so not sure which is right. Neither works however.

Any help is greatly appreciated.

Answer 1

You've neglected to do this: "Copy the .gbdinit file to your home directory"

It defines dump_bt user function.
