Introduction
This document provides the steps to retrieve information from the Cisco Content Service Switch (CSS) to determine why your CSS crashes. This information helps Cisco Technical Support engineers to find the cause of the reboot. If a bug is encountered that is already fixed, a recommendation is made accordingly.
Prerequisites
Requirements
Readers of this document should have knowledge of these topics:
-
Use of the CSS debug feature llama.
Components Used
The information in this document is based on these software and hardware versions:
-
CSS 11000 - End of Sale
-
CSS 11500
-
CSS 11800 - End of Sale
-
WebNS software
The information in this document was created from the devices in a specific lab environment. All devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.

Background Information
Problem
When a CSS reboots unexpectedly, it usually leaves behind some clues about why it crashed. The most important step is to gather the information that is available to determine the cause, and find a quick solution to the problem.
Solutions
The solution is to check for a mini-dump record that can be in NVRAM.
CSS 115xx and CSS 11xxx Platforms
The output in this section is specifically for the CSS 115xx platforms.
-
Login and enable the llama debug.

You might need the core file that is left behind. In order to check for files that are left behind, issue the show core command.
CSS501-1(debug)# show core <No files available>
If the core files are available, you get a list that displays the core files with the time, date stamp, and the size. Check the timestamp to identify the most recent core files.
Note: If the file is 130024448 bytes, or does not have a file name with .gz on the end, it is not compressed. Compress the file before you copy it from the machine. See the Compress the File section for more information.
CSS 118xx Platforms
The output in this section is specifically for the CSS 118xx platforms.

You might need the core file that is left behind. In order to check for files that are left behind, issue the show core command.
css800-1(debug)# show core SFM0601_5.00_25.0 JUL 23 15:32:36 130024448 SFM0601_5.00_204.0 NOV 6 14:38:04 130024448 css800-1(debug)#
If the core files are available, you get a list that displays the core files with the time, date stamp, and the size. Check the timestamp to identify the most recent core files.
Compress the File
The procedure in this section is specifically for the CSS 118xx platforms. In order to compress the file, login and enable the llama debug.
llama compress c:/Core/
This places you in debug mode and compresses the file. The compress takes a considerable amount of time, and places extra load on the CPU.
FTP From Your Workstation to the CSS
The procedure in this section is specifically for the CSS 118xx platforms.
Once the file is copied from the CSS, initiate an FTP from your workstation to the CSS to compress the file.
ftp login: admin passwrd: cd Core binary get bye
Note: The CSS does not support passive mode FTP.
Extract Important Core Information for Cisco Technical Support
Issue these commands on the UNIX machine to view the first fifteen lines of the core file. They contain important text information that identifies the problem.
strings | head -20 or gzcat | strings | head -20
Note: In order to determine the cause, send this information to Cisco Technical Support. In order to fix any outstanding bugs, be prepared to FTP your core file to Cisco Technical Support for analyisis by the WebNS developers.
