ABRT Internal system error
1. Retry the command at 1-minute intervals up to 5 times.
2000 ABRT Response to the test was not received within the allowable time period.
This may be due to hyperactivity. Error Type 1538 in the error log indicates
hyperactivity. The hyperactive circuit pack is out of service, and one or
more of the following symptoms may be exhibited.
● The UDS1-BD tests (such as Tests #138 and #139) are aborting with
Error Code 2000.
● The tests run on the ports of this circuit pack are returning a
no-board result.
● A busyout or a release command has no effect on the test
results.
● A list config shows that the circuit pack and the ports are
properly installed.
When hyperactivity occurs, the circuit pack is isolated from the system, and
all of its trunks are placed into the out-of-service state. The system tries to
restore the circuit pack within 15 minutes. When no faults are detected for
15 minutes, the UDS1 interface circuit pack is restored to normal operation.
Every UDS1 interface trunk is returned to the in-service state. Hyperactivity
is often caused by the associated facility. In such a case, faults (such as
slips, misframes, or blue alarms) are entered in the error log. In addition,
many hardware errors are logged against the associated trunk circuits. If
the facility is OK and the error occurs again after 15 minutes, replace the
circuit pack.
2100 ABRT Could not allocate the necessary system resources to run this test.
1. Retry the command at 1-minute intervals up to 5 times.
