Hi, I think i got the clue. This problem disappears when i restart ejabberd server and destroy existing rooms. However problem starts to re-appear after some time.
I get a hint that max_user_conferences which defaults to 10 is the problem here. As user imjaxlim tries to enter 11th room, it starts getting 503 error code, while other users do not. Though now it is out of jdev list probably, can I set custom max_user_conferences for specific users? Thanks for the help. -- Abhinav Singh, Founder, Jaxl Inc.
