Title: Troubleshooting high memory utilization

1) A switch works properly. However, the show memory command output shows that the memory utilization rangesfrom 80% to 90% or even higher and increases continuously. (As the availablememory is decreasing, the memory utilization is increasing.)

2) If the memory utilization increases till the memory is exhausted, thefollowing symptom appears:

When you type characters on the console port, the switch does not respondand a log indicating insufficient memory is displayed.

not enough memory! cli execute fail!

Or *Sep 6 08:54:14:%SCHED-0-NOSTACK: Could not allocate 40960 bytes for stack from memory.

Note: Some Ruijie switcheshave a small memory. After they are started, memory utilization ranges from 50%to 75%. When switches are running, the memory utilization may even exceed 80%.As long as the switches work properly and the memory does not increase to 90%or above sharply, no fault occurs.

Check whether the memory utilization increases continuously. If thenetwork management software shows that the memory utilization increasessharply, a memory leak may have occurred.
