system was functioing well, when suddenly telnet session hung and then I got the following message "Bus error(coredump)"

would appreciate if anyone would assist as to what to do next.

first thing to do is find out what core dumped. Was it telnet or something else? Your troubleshooting starts there. If you have the core file, and you are skilled in debugging/viewing core files (or have someone in your team/office) then start there. That file will give you the source line before the core occurred

Also check 'errpt' and the code on the front of the box. I've seen this with bad sysplanars.

appreciate the response.

I do try errpt and output is
marmaduke--root::/>errpt
ksh: errpt: 0403-006 Execute permission denied.

also tried a snap utility with the following commands that i read up, that too gave the same message.

marmaduke--root::/>snap -gfkDNGL
ksh: errpt: 0403-006 Execute permission denied.

Iam reading through some more papers, will let you know.
