Hi

     I have enable automatted Idle disconnect settings in Client Connections page at Server settings. I have attached the snapshot of the settings.

     Openfire doesnot disconnect all the idle connection if same user logged in with different resource.

     I am using Openfire 3.7.1

     I am connecting via BOSH concept.

     Please Help me to fix the problem.

     Thanks in advance
