Dead sessions not dropped

When a user turns off or reboots a client PC, the network connection breaks. If this happens during a data transfer, TAS notices immediately and terminates the appropriate process. If it happens when no traffic passes between client and server, TAS notices only after a few minutes. This timeout period, dependent on the host system, typically lasts about five minutes. After the timeout period elapses, TAS terminates the appropriate process.

TAS, by default, relies on the host's underlying transport layer keepalives to keep track of dead sessions. If other applications, such as telnet, do not drop dead connections, the transport vendor may not have keepalives implemented. You may have configured TAS to use NetBIOS keepalives instead by changing the keepalive attribute at realm ->Manage File Services->[select the service]->Administer ->Configuration or with the tnservice command.
