3.3.6.2 Idle Connection Timer Event
The Idle Connection Timer (section 3.3.2.2) SHOULD periodically trigger a scan of existing SMB connections and disconnect, as specified in section 3.3.7.1, those on which no opens exist (Server.Connection.FileOpenTable and Server.Connection.SearchOpenTable are both empty) and no operations have been issued in the last Server.AutoDisconnectTimeout minutes (Server.Connection.IdleTime has passed). For each session in the disconnected connection, Server.Statistics.sts0_stimedout MUST be increased by 1.
