The Five Minute Load Average Is Abnormally High—Maintenance (55) - Cisco BTS 10200 Troubleshooting Manual

Troubleshooting Maintenance Alarms
The Five Minute Load Average is Abnormally High—Maintenance (55)
The Five Minute Load Average is Abnormally High alarm (major) indicates the five minute load average
is abnormally high. The primary cause of the alarm is that multiple processes are vying for processing
time on the system, which is normal in a high traffic situation such as heavy call processing or bulk
provisioning. To correct the primary cause of the alarm, monitor the system to ensure all subsystems are
performing normally. If so, only lightening the effective load on the system will clear the situation. If
not, verify which process(es) are running at abnormally high rates and provide the information to Cisco
TAC.

Memory and Swap are Consumed at Critical Levels—Maintenance (57)
Maintenance (57) is issued by the BTS 10200 system when memory consumption is greater than 95
Note
percent (>95%) and swap space consumption is greater than 50 percent (>50%).
The Memory and Swap are Consumed at Critical Levels alarm (critical) indicates that memory and swap
file usage have reached critical levels. The primary cause of the alarm is that a process or multiple
processes have consumed a critical amount of memory on the system and the operating system is
utilizing a critical amount of the swap space for process execution. This can be a result of high call rates
or bulk provisioning activity. To correct the primary cause of the alarm, monitor the system to ensure
all subsystems are performing normally. If so, only lightening the effective load on the system will clear
the situation. If not, verify which process(es) are running at abnormally high rates and provide the
information to Cisco TAC.

No Heartbeat Messages Received Through the Interface—Maintenance (61)
The No Heartbeat Messages Received Through the Interface alarm (critical) indicates that no HB
messages are being received through the local network interface. The primary cause of the alarm that the
local network interface is down. To correct the primary cause of the alarm, restore the local network
interface. The secondary cause of the alarm is that the mate network interface on the same sub-net is
faulty. To correct the secondary cause of the alarm, restore the mate network interface. The ternary cause
of the alarm is network congestion.
