1. Execute the
display system internal kernel memory pool
command multiple times
to identify the memory portions that show an unexceptionally utilization increase.

Each value line shows the memory information for a memory portion. The product of the
Number and Size fields shows the capacity of the memory portion. If the capacity of a memory
portion continually increases, the memory portion is being continually used. To determine
whether there is an issue with the memory portion, you must observe the capacity change and
change speed of a memory portion for a period of time. The memory leak process might be slow
and you might need to spend a long time (even weeks) observing the leak symptom.
2. Save the information displayed in the previous step and contact H3C Support.
IMPORTANT:
For quick troubleshooting, do not reboot the device before you contact H3C Support. The previous
step only identifies the memory portions that have issues. Further information is required to locate
the code section that has issues.
