Prerequisites Requirements Cisco recommends that you read Troubleshooting Router Crashes before proceeding http://www.cisco.com/c/en/us/support/docs/ios-nx-os-software/ios-software-releases-121-mainline/7949-crashes-buserror-troubleshooting.html with this document. Components Used The information in this document is based on these software and hardware versions: All Cisco IOS® software versions All Cisco routers Note:This document does not apply to Cisco Catalyst switches or MGX platforms. The information in this document was created from the devices in a specific lab environment. All of the 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. Conventions Refer to the Cisco Technical Tips Conventions for more information on document conventions. Identifying Bus Error Crashes 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). A bus error can be identified from the output of the show version command provided by the router if not power-cycled or manually reloaded. If you have the output of a show version or show technical-support command (from enable mode) from your Cisco device, you can use it to display potential issues and fixes.

The painful reality is that performance is acceptable day after day, until quite suddenly it all falls apart. cpu_0 received a When this happens, the administrator needs to be prepared to help the organization get through the crisis.Computer applications are growing ever more intelligent and easy to use. One of the by-products of making applications easier to use is that they usually also require more resources to run. And wherever productivity is a central factor in the decisions you make, performance considerations loom large and continue to play an important role in system management.Are you wondering, for example, if more expensive equipment would give better performance? The answer is often yes, but not always. This book will show you why it is important to understand the performance characteristics of the hardware and of the workload, and how they match up against each other. Windows 2000 Performance Guide takes you through problem solving techniques like measurement methodology, workload characterization, benchmarking, decomposition t

ETAPS is an annual federated conference that was established in 1998 by combining a number of existing and new conferences. This year it comprises ve conferences (FOSSACS, FASE, ESOP, CC, TACAS), four satellite workshops (CMCS, AS, WAGA, CoFI), seven invited lectures, two invited tutorials, and six contributed tutorials. The events that comprise ETAPS address various aspects of the system - velopment process, including speci cation, design, implementation, analysis and improvement. The languages, methodologies and tools which support these - tivities are all well within its scope. Dieren t blends of theory and practice are represented, with an inclination towards theory with a practical motivation on one hand and soundly-based practice on the other. Many of the issues involved in software design apply to systems in general, including hardware systems, and the emphasis on software is not intended to be exclusive.
