ALM-303046691 Memory Usage Reached the Threshold

Description

ENTITYTRAP/2/MEMORYUSAGERISING: OID [OID] MEMORY utilization exceeded the pre-alarm threshold.(Index=[INTEGER], HwEntityPhysicalIndex=[INTEGER], PhysicalName="[OCTET]", EntityThresholdType=[INTEGER], EntityThresholdWarning=[INTEGER], EntityThresholdCurrent=[INTEGER], EntityTrapFaultID=[INTEGER])

The memory usage of the system reached the alarm threshold.

Attribute

Alarm ID	Alarm Severity	Alarm Type
303046691	Critical	equipmentAlarm

Parameters

Name	Meaning
OID	Indicates the MIB object of the alarm.
Index	Indicates the entity index.
HwEntityPhysicalIndex	Indicates the physical entity index.
PhysicalName	Indicates the physical entity name.
EntityThresholdType	Indicates the threshold type.
EntityThresholdWarning	Indicates the alarm threshold.
EntityThresholdCurrent	Indicates the current value.
EntityTrapFaultID	Indicates the error code.

Impact on the System

If the threshold is not high (for example, 50% or 60%), services are not affected. If the threshold is high (for example, 80%), it may have the following impacts:

Services cannot be allocated with memory and become unavailable.
The storage medium has insufficient space, affecting log functions and software upgrades.

Possible Causes

The memory alarm threshold was low.
The device provided too many services.
The device memory leaked.

Procedure

Run the display memory-usage command to check the alarm threshold for memory usage to determine whether the alarm threshold is set properly.
- If so, go to step 3.
- If not, go to step 2.
Run the set memory-usage threshold command to set a proper alarm threshold for memory usage. After that, check whether the alarm persists.
- If so, go to step 3.
- If not, no further action is required.
Delete unnecessary services and configurations to reduce memory usage.
- If this alarm persists, go to step 4.
- If the alarm is cleared, no further action is required.
Collect alarms, logs, and configurations, and then contact technical support engineers.
