Recovering From a Failure of the
camAuditor Process
Background
Our engineers are aware of a rare condition that can cause the camAuditor
process of the Digital Network Control System (DNCS) to fail. When the
camAuditor process fails, Entitlement Management Messages (EMMs) are not
updated and the emmDistributor process transmits expired EMMs to Digital
Home Communication Terminals (DHCTs). When DHCTs fail to receive updated
EMMs, they may time out and become inoperative.
Although rare, this condition is most likely to manifest itself under one of the
Although rare, this condition is most likely to manifest itself under one of the
following circumstances:
DNCS processes are restarted all together (using dncsStart)
The cam processes are started as a group (rather than element by element)
through the dncsControl utility
Should the camAuditor process fail under these circumstances, the indicator light
for the camAuditor process will still illuminate green on the DNCS Control
window, so system operators will not know that the camAuditor process has
failed. Therefore, system operators should monitor their system for the three
following symptoms that indicate that the camAuditor process may have failed.
The field in the Doctor Report called DHCTs with EMMs Expiring in 15 Days
indicates that the site has DHCTs with EMMs expiring in 15 days or less.
Important: Our engineers wish to remind system operators to run the Doctor
Important: Our engineers wish to remind system operators to run the Doctor
Report daily.
Output from the smMix utility shows in-service DHCTs set to expire within 20
days.
The log file for the camAuditor process shows no entries.
Our engineers have assigned Change Request (CR) 84069 to this issue and are
actively working on a solution.
