- Consider : https://www.cisco.com/c/en/us/support/docs/wireless/wireless-lan-controller-software/200046-tac-recommended-aireos.html and upgrade the controller accordingly , if applicable -> check if that can help.

(for 9800 based platforms , use 17.9.4 , if applicable)

Is the WLC time set correctly (NTP)?
Is so, then no recent software core dump, so that would suggest a power or hardware issue.
