Greg,
Thanks. Regarding the suspected corrupt dump file. In the syslog I can
see the dump file being created (actually 'vmcore') and there are no
error messages. Are you saying that the corruption occurs during
the writing of the file or is the data resident in memory corrupt?
I suspect that something is wrong with the hardware on this
box. We moved the hard drive from one motherboard to another but the
problem remains. This leaves the hard drive as suspect but there are
no syslog messages to indicate a drive problem. The system is running
4.8 p13. Thanks.
Kent

Can you tell me what I am doing wrong? Thanks.
Unfortunately, this looks like you have a corrupted dump. What you've
done (with the exception of exit) is correct. You might find it
better to use serial debugging if this is repeatable.
