As I said in title, we can't see any nodes and overview in admin studio often. our on-premise cluster.
I understand this is fixed as long as restarting pega tomcat.
But I want to know the cause not to occur like this.
I noticed in log below, does anyone how about this ?
rationsDistributedExecutorImpl) ERROR - Caught exception while getting result from future object (perations.ClusterManagementAPI) ERROR - exception while fetching high level node info for the node c579ea6
