Hello
I have encounter this same problem before .I am using user manager as radius on licence level 4 . There clash between hotspot active user and user manager active session . So when there was more than 20 user online on hotspot i got that error . I am not sure about problem but when I switch to another radius i got it solved . Please contact mikrotik support for be more sure.
Thanks
Regards
Nikem
