Run the command `(allssh free -mh)` on one of the CVMs and check whether it affects only one CVM or all the CVMs across the cluster.

How many nodes does the cluster have? It is recommended to assign 32 GB of memory to each CVM.

I also faced a similar issue with the version:

* The cluster is running:

+ AOS 6.1

+ AHV 20201105.30142

+ NCC 4.5.0.2

I performed the rolling restart (https://portal.nutanix.com/page/documents/kbs/details?targetId=kA00e000000kALCCA2). to fix these , restart was suggested by support engineer after reviewing the logs 

to the issue for forever i had upgraded the AOS version 

 I would suggest to consult support to review the logs and find root cause
