I have an installation of 5 x IAP205s. They have all gone through the initial configuration, have discovered each other and all are visible from the GUI presented by the virtual controller. However, when I make a configuration change from the GUI it does not replicate to two of the five access points (the configuration delta from the "show delta" command doesn't change to the new version shown by the VC). And error messages like those below are shown in the log of the VC.
