Field Notice: Editing the processes.dat file Causes procM Core Dumps

June 21, 2001

Products Affected

The products affected are the Cisco VSCSC2200 and the Cisco VSC3000.

Problem Description

If the processes.dat file in the Cisco SC2200 or VSC3000 is modified using a UNIX editor, an instability in the system could result. This instability manifests itself in core dumps in procM.


This issue has been seen in Cisco test labs.

Problem Symptoms

Core dumps in procM occur after the processes.dat file is modified.


The processes.dat file should not be modified from the system configuration shipped with the release. If the processes.dat file is modified and causes procM core dumps, call the Cisco Technical Assistance Center (TAC). The TAC will bring down both units of the SC2200 or VSC3000 simultaneously, ensure that the processes.dat files are identical on both devices, and then bring them back in service.
