I have a Cisco 5520 wireless controller on 8.5.151.0 that is currently experiencing this bug:
CSCvq41340 - Data Plane reloads unexpectedly
User Crash: The system has encountered a fatal condition at broffu_fp_dapi_cmd.c:4938 #Last time was User Crash: The system has encountered a fatal condition at broffu_fp_dapi_cmd.c:4935
I have a TAC case open but am curious if anyone was able to resolve this issue. If so, what was your fix or workaround?
