Hello,
we have a strange problem with our EX3300 series switches virtual chassis (VCs), running Junos 12.3R3.4. Most of them running over years without an issue, but since the last month we where faced with two VCs comming up, after an environmental powerloss, with new ssh hostkeys.
I did not find any hint or documented procedure where Junos is doing this by itself.
Any hints and help in this case are welcome!
