Session suddenly disconnected while working on TSUBAME3

For TSUBAME3, session timeout is set for security measures.
Sessions that do not have any input at a certain time are disconnected.
Even if the GUI application is started up and operated, if there is no input to the terminal, it will be disconnected.

If you want to avoid this, please set keep alive on the terminal side.
Please check the user guide of the terminal for keep alive setting.
