Core file analysis

Pouchie1 · August 2, 2009, 3:30pm

How can we analyze a core file and determine why it was generated on a solaris system?

I know file core filename will tell us what program generated the file. But, what to do next to get more details?

Thanks,

This might give clues:

PATH=$PATH:/usr/proc/bin
pargs core
pstack core
pflags core
pldd core
pmap core

Of those listed, the "pstack" utility is probably the most useful.

Even better, you can use "dbx" from Sun Studio compiler suite.

file core

e.g.
core: core file from 'cat' - received SIGQUIT

strings core

A bit of a random approach but will sometimes reveal what the program wanted to tell you. (Like "cannot create semaphore").
