Refer " LRADIF_INTERFERENCE_PROFILE_FAILED" from the link given below

Basically, it is saying that AP detected an interference which exceeds the threshold value set under WLC --> RRM settings. You can configure threshold to create a trap for interference. 

You can tune the threshold values under RRM or do a RF spectrum analysis to identify the source of interference and mitigate/remediate it.

You can also use WLC Config Analyzer Express to review RF state of the network.

Also note that in dense deployment, it is common to see 2.4GHz Co-Channel Interference and it may not be possible to eliminate this.
