I have some devices that are constantly in a learning state and after a couple of hours they go into a questioned state. I am running DFM 3.0.3 (LMS 3.0.1), normally in the past I would re-initialize the database. Is there any other way to get around this annoying behavior in DFM.
This is most likely a bug. If the questioned devices are reporting that they are questioned due to an internal error, then you need to contact the TAC, and get a class file patch for this problem. This has been fixed in LMS 3.1.
