Core Dump Analysis Using PStack and PMAP

Hello,

I'm new to the group and this is my first post. I'm hoping someone can help me out. I have a core dump that I need to analyze from a Unix box and I've never done this sort of thing before. I was told to run a pmap and pstack on the core file which provided two different output files. I've been searching on Google for information on how to read these files to determine the culprit of the crash but I'm not having much luck. I've read many articles about gdb but I don't have root access on the system to add the tool.

Can anyone point me to a good tutorial or provide tips on how to analyze the core dump file with the pmap and pstack files I have?

Thanks so much.

Kimmy
