objects keep going off scan and require the engines to be redeployed

Hi Everyone

I am currently facing a problem of objects that keeps going off Scan I would like to know why this is happening.

On the SMC warnings that keep appearing are as follows:

Fail to create bootstrap on a remote node 

Platforms x exceed maximum heartbeats timeout of 8000ms

Failed to communicate with target node, This may be because it is not connected to the same System Managment server.

Thank you
