his error type indicates that the circuit pack sent a
large number of control channel messages to the switch within a short
period of time. If error type 1538 is also present, then the circuit pack was
taken out of service due to hyperactivity. If error type 1538 is not present,
then the circuit pack has not been taken out of service, but it has generated
50% of the messages necessary to be considered hyperactive. This may
be completely normal during heavy traffic periods. However, if this error
type is logged when the circuit pack is being lightly used, it may indicate a
problem with the circuit pack or the equipment attached to it.
