Troubleshooting a Process Restart
A process restart does not typically cause a major problem for the network, nor does it typically cause a
loss of traffic. However, it can be helpful to troubleshoot the event, to find out why the process crashed,
and whether you need to consider taking any action to locate or correct a problem.
To troubleshoot a process restart, contact Cisco Technical Support. For Cisco Technical Support contact
information, see the “Obtaining Documentation and Submitting a Service Request” section on page viii
in the Preface.
Collect the following information before contacting Cisco Technical Support.
• show context all location all command output
• show version command output
• show dll command output
• show log command output
• Collect core dumps. See the “show context Command” section on page 1-11 for information on how
to collect core dumps.
