Analyzing a core dump

[gwichman]

What commands can one use to analyze a core dump? I've got a lotus notes app that's dying when i try to start it and hoping to shed some light as to why.

Will give the application or program caused the core file:
lquerypv -h /path_to_core_file 6b0 64

Will give the exact location of the binary or shell script which caused the core file:
strings /path_to_core_file | grep “_=”

ok not terribly useful. The first one didnt seem to show what program caused the core file. I know what file creates the core file because i ran it and watched it happen =). What i don't know is why it's core dumping.. Everything seems to be setup correctly.

Unless you have the source so you can run dbx against it and find where it is failing, then the vendor will have to be involved to find the cause.
