Stopping and Starting the DNCS
Processes Correctly
Background
Engineers from Cisco® Services are aware of several instances where system
operators of the Digital Broadband Delivery System (DBDS) have attempted to
stop or restart a system process through the command line of the Digital Network
Control System (DNCS). Our engineers urge system operators to avoid stopping
or restarting system processes in this manner. A restart of a system process from
the command line may result in multiple instances of a single process to be
running at the same time. Furthermore, system operators who stop or restart a
process from the command line of the DNCS bypass the safeguards that have
been engineered into the DNCS.

should use to stop or start a system process.
Considerations About Stopping and Restarting System Processes
Engineers from Cisco Services wish to remind system operators that stopping and
restarting a system process is an acceptable workaround to some minor
conditions that may affect the DBDS from time to time, provided the processes are
stopped and restarted properly. However, system operators should be aware that
a regular need to stop and restart a system process may mask a deeper,
underlying issue.
If system operators discover that they need to stop and restart a process with
If system operators discover that they need to stop and restart a process with
regularity, they should save the appropriate log files, open a case with Cisco
Services, and then send the log files to our engineers for analysis. System
operators should contact Cisco Services for assistance in identifying which log
files to save.
