I have two identical machines running PRTG. The master node will start to eat up system memory overtime while the failover node is connected. Once failover is disconnected by setting it inactive or stopping core server service, there is a huge drop and memory is freed up. It's to the point that over a few hours the Master gets to a low 20% health or almost crash. I have taken PRTG completely off both and reinstalled but will do the same. Any suggestions to fix this ?
