They did not find anything obvious, but they did reseat the coax and ethernet cables and oddly enough, we now have no messages in the syslog (other then login notifications). It has spooked us to be looking for something that can replace that, I mean you should really have spares on hand, so moving forward with trying to find something. The vendor we were hoping to find some refurbs at though does not have any and I'm not surprised to learn the models we have are EOL.
