I couldn't find any loop in the network. When we restart Mikrotik CHR, there will be nor such error for the next 24 hours. Can you please help me to resolve the issue. All the mac addresses displayed in the log are, VMWare, Mikrotik, and some other switches none of them belongs to user end devices.
