We are using a Sophos UTM 9.3 HA Cluser on Hyper-V. The cluster worked fine, but after some time we noticed that the 2nd node had shut down. When we power on the virtual machine it boots like normal, but just after that we get the message "blogd: can not set console device to /dev/pts/0: Device or resource busy", and the UTM VM shuts down again.
Does anyone have an idea what causes this, and more importantly, how to fix it?
