You have a bad WLC. You will have to RMA that. I have seen that in the past and others here have also went through the same thing. Open a TAC case and tell them that it was DOA and they will replace that with a new unit.
i have the same problem but i reboot and save config the device after months when i got the 0 access points supported on WLC after reboot all the new configuration weren't saved only the old configuration from 2 to 3 months old
and on AP i got the max no. of ap has reached
and those AP that dis-joint were joint to wlc a day before
the wlc supported 50 ap only 7 are joint and 11 were disjoint after 2 months
If you make changes and save, then issue a reboot right after. When the controller comes back online and the configuration is not there, then you have a bad controller and you need to get that replaced.
