Hardly, I already do enough of that <G>...

First, let me say I have the utmost repsect for Tony and his opinions and
certainly his treasure trove of a web site.  Perhaps it is because I was a
systems programmer (Xerox CP-V) in a former life but the crash tool and
the dump from a crash do provide important clues beyond the panic display
like the currently scheduled processes.

One excellent reason to go this route is the thought of having a novice
try to write down all those registers and hex contents without making a
mistake, not to mention the time required while their users are breathing
down their neck.  (I am nearly an hour away so I can't just pop over
myself.)

In this case I ARE the consultant (bad grammar intentional for emphasis)!

I like Tome Melvin's script which runs the crash analysis:
        panic
        stack
        trace
        user
        proc, and, of course,
        quit

 against the dump and emails the result though I might be tempted to save
the dump to a file before cleaning it out of swap all without requiring
any user intervention or delaying the system's coming back up.

Thank you,
Lucky
