We can have many reason for the high utilization of memory on that CVM and we may need to look at the CVM logs to understand the cause.

 

Prior to 5.1.x versions we have noticed that multiple service leaders might be running on the same CVM and that can cause a memory spike. If thats the case then you can try upgrading the AOS to 5.1 or higher. 

 

However i would recommend to have a support case opened to troubleshoot the issue.
