RRM - "Cannot start RRM analysis, please wait for the network to become stable."

Hello,

I have two teamed controllers MSM765 and 62 access points (MSM460 & MSM466). For a few weeks, I am not able to start an RRM analysis. Neither manually, nor scheduled. Error message is:

Cannot start RRM analysis, please wait for the network to become stable.

According to the documentation, "stable" is defined as:

All controlled APs are synchronized with the configuration settings on the controller.
The number of controlled radios in the network has not changed during the last 30 minutes.
No controlled radio in the network has had its configuration changed and synchronized during the last 30 minutes.
The majority (at least 99%) of the controlled APs in the network are operational and communicating with the controller.
All controlled radios have been operational for the Neighbor detection time (shown on the Radio configuration page for each radio).
The controller has received RF environment information from all controlled APs.
If operating in teaming mode, all team members are operational and synchronized with the team manager

I checked all of them, and they are fulfilled. The only one I don't know how to check is the underlined one: Is there a log entry for receiving RF environment information? Can I enforce APs to send RF environment settings?

Does anyone have an idea on how this situation can be resolved and RRM can be used again?

HPE support found the cause. One access point was repeatedly losing connection to the controller (exactly every 5 minutes for some strange unknown reason). After factory resetting the access point, the situation stabelized.

Here's the log entry that uncovered the problem (from Team >Tools > System log > Unfiltered log):

Sep 11 14:01:53.365 warn 00:24:A8:XX:XX:XX rfmgr_sc: RRM message channel to AP [98:4B:E1:XX:XX:XX] lost connection
