Hello, I have been working over the last few months to try and get to the bottom of why our apache processes are regularly being killed with a Sig 11 (Segmentation Fault). Here are the messages in the kern.log

However when I enabled coredump's in apache I don't get anything. I can however get a dump if I send a manual sig 11 to the process. Which brings me to my questions. Is there a method or way that I can enable a 'debug' mode in php which would help me track down and identify the root cause of these problems? If anyone has any suggestions on what I can do to try and get further down the track to enlightenment I would be really appreciated.
