Hi all, we have 50+ nodes around this particular DCC group. two of the nodes, in different ospf areas will go gray after a few hours of having ctc open. I can still ping the shelves (from the machine ctc is running on) and if I reload ctc they reappear just fine (for another hour or so). The problem seems to have just popped up in the last week. We are unaware of any changes to the network that would be related.
Has anyone seen something like this before? They are on difference software versions... one is 7.22 one is 7.23. One is a 15310MA and one is a 15454.
