Troubleshooting System Alarms
Software Error—System (12)
The Software Error alarm (major) indicates that a software error has occurred. The primary cause of the
alarm is that a logic path is not handled by algorithm in the code. To correct the primary cause of the
alarm, save the trace log from around the time of occurrence and contact Cisco TAC.
Note
Refer to the
“Obtaining Documentation and Submitting a Service Request” section on page lvi
detailed instructions on contacting Cisco TAC and opening a service request.
Multiple Readers and Multiple Writers Maximum Q Depth Reached—System
(13)
The Multiple Readers and Multiple Writers Maximum Q Depth Reached alarm (critical) indicates that
the MRMW maximum queue depth has been reached. The primary cause of the alarm is message
flooding from an erratic network element. To correct the primary cause of the alarm, check the messages
to process, The secondary cause of the alarm is resource congestion or slow processing of messages from
queue. To correct the secondary cause of the alarm, check the process and system resources. The system
may need to be failed over.
Multiple Readers and Multiple Writers Queue Reached Low Queue
Depth—System (14)
The Multiple Readers and Multiple Writers Queue Reached Low Queue Depth alarm (minor) indicates
that the MRMW queue has reached the low queue depth threshold. The primary cause of the alarm is a
high rate of messages from the network. To correct the primary cause of the alarm, check the messages
to the system. The secondary cause of the alarm is system or processing thread congestion. To correct
the secondary cause of the alarm, check process and system resources.
Multiple Readers and Multiple Writers Throttle Queue Depth
Reached—System (15)
The Multiple Readers and Multiple Writers Throttle Queue Depth Reached alarm (major) indicates that
the MRMW queue has reached the throttle depth. The primary cause of the alarm is that inbound network
messages arriving at a rate much higher than processing capacity. To correct the primary cause of the
alarm, determine the cause of increase in inbound network traffic, and try to control the traffic
externally. The secondary cause of the alarm is that there is resource congestion resulting in a slow down
in processing messages from queue. To correct the secondary cause of the alarm, check the platform
CPU utilization, IPC queue depths and overall availability of system resources.
