We have a DX90 S2 which started losing MNT connection about one week ago. That means you cannot connect to both CMs via SSH, HTTP or HTTPS. You can still ping both CMs though.
I then have to pull out the slave CM for it to restart, then I can SSH into it and can issue the change master command and then everything is working fine for a few days until it happens again.
Is this a known behaviour? The most current firmware is already installed so I don't know what to do.
Thanks in advance!
