[c-nsp] 7200 Bus error crash and strange disk error

Sun Oct 10 08:03:23 EDT 2004

i don't think the two errors related.  use the output interpreter and
go from there
https://www.cisco.com/cgi-bin/Support/OutputInterpreter/home.pl?locale=en
pasting show context come back with some sort of memory problem which
seems to correspond to the show region.

STACK DECODE NOTIFICATIONS (if any)

ERROR: This router was last restarted by a bus error.
The system encounters a bus error when the processor tries to access a
memory location
that either does not exist (a software error) or does not respond
properly (a hardware
problem).
TRY THIS: A Stack decode will occur (see below), and will assume this
is a software
error. If the result is not accurate, try pasting an enabled 'show tech-support'
into Output Interpreter to confirm if the cause is software or hardware related.
NOTE: The enabled 'show tech-support' must contain the 'show region'
command. 'show
region' was first included in 'show tech-support' in IOS 12.0(9). Use
the Troubleshooting
Bus Error Crashes document to assist in troubleshooting

The failure was caused by a software defect.Note that this is a bus error crash
and can also be hardware related.Please read Troubleshooting Bus Error Crashes
for more details,especially if no bug from the list seems to match your issue.

The stack trace decoded symbols are:
	std_console_putc
