I believe that the value of limitStreamViewersMaxViewers is only utilized if there is no specific limit for the given stream. When a new connection is initiated, it checks to see if that stream has a specific number associated (i.e. myStream=20) and compares the current count to that value. If that does not exist, it will use the default value as specified by the limitStreamViewersMaxViewers property.
If you are seeing a problem within that workflow, please zip up your conf/ and logs/ and send them to email@example.com and reference this post for further review.
Kindly note that Iíve that issue with limitation, limitStreamViewersMaxViewers is 25 connection but the dashboard showing more than 25 connection as shown in attachment (Note: the limitation working fine on 25) , in addition Iíve added the other module limitStreamViewersMaxViewers and set limit to 25 , too without any achieves about dashboard counter.
