Thanks for replying!

The suggestion in that thread, though - to reboot everything - isn't really a solution.  At best it's a very hacky workaround, and one that would probably need to be repeated on a regular basis until the problem is actually fixed.  I've already rebooted the OC200 (and I'll do that once more), but even that was really a desperate last resort!

Please can you ask the TPL technical teams to investigate the root cause and come up with a permanent solution?  Clearly full data from all of the network devices - including details of which devices are connected to which ports - is successfully being delivered to the controller, because all the other functions are still working, so this problem is specific to the graphical topology map.

Maybe part of the answer is to provide a simple non-disruptive way of forcing a data resync - without requiring a reboot, and certainly without requiring a reset and re-adoption (which I notice is currently the only way to re-apply some areas of configuration, such as CLI commands).
