Hi Dewi,
Please refer the article shared by Sanjay in his previous comment.
Also make sure there is no network issue and APs are able to reach controller (master AP) all the time.
If you do not find any network issue and APs are still rebooting due to heartbeat lost, please contact support and report the issue.
Regards,
