Joseph,
This sounds like a good time configure the router to dump the core to a
TFTP server before the next crash. Here is a link from Cisco's webpage and a
little cut from the page:
#######################################################################
http://www.cisco.com/warp/public/68/15.html
Creating a Core Dump Using TFTP
If the core dump is 16M or less, you can use TFTP with the following global
configuration command:
exception dump <IP address of Remote Server>
Including this command in your configuration causes the router to attempt to
make a core dump if it crashes. The core dump is written to a file named
"hostname-core" on your TFTP server, where "hostname" is the name of the
router. You can change the name of this core dump file using the exception
core-file <filename> command. The name you choose using this command must
already exist in the /TFTPBOOT directory of the Remote Server. The core dump
file will be the size of the memory available on the processor.
Here is an example going to the server at IP address 161.171.10.3:
exception dump 161.171.10.3
Note:
For core dumps greater tham 16M, you must use either RCP or FTP. TFTP won't
work.
#####################################################################
Don't ask me how to figure out if your core dump will be over 16M. Trial
and error would be my process.
Then what you would want to do is work with Cisco and have them analyze
the output, unless you are proficient in this.
As Leon mentioned you could do the show stacks command after a crash and
copy the stack trace into the stack decoder on Cisco's website it is also
important to note what it says on the show stacks command for why the crash
occured for instance:
System was restarted by error - a Software forced crash
The time I sent off a stack trace my reply from Cisco didn't have any
usefull information, I talked to a friend of mine and he said it hasn't ever
replied with helpfull info, but I'd try that first. I can't find the link
now for the stack decoder, but I know it is on the CCO TAC page, and if you
go into the groupstudy history and find Andrews reply to my question subject
"RE: stacks decoder" the link is there. The more specific logging sounds
like a good idea, too. I'm trapped at work on a Saturday, so I look forward
to your future postings. Good luck!
