Adopt problem between RFS7000 & AP300

[k3nshjnz]

Hi all,

After one night, our network has a big problem, our AP 300 is  constantly adopted and unadopted with Controller RFS7000 (Please find the attachment file for more detail.)
It make our client has a terrible connection. I try to reboot Controller sometimes, but it's can fix.

Please give me a ideal and help me out of this problem.
Thanks so much
