Participant's connection becomes lost (white signal) and stays in the meeting indefinitely(85 hours)!

Our inactive participant stayed inside the meeting for 85 hours. Did someone face this same issue? Can anyone suggest some solution to this?

by “our”, did you mean your hosted server?
and there is a limit in too. how could your participant even be in a room for 85 hours…! because once you are incative or leave you are already out of the room. Please provide more details about your setup and problem. Thanx

Do you have custom Prosody module?
