 When running in client-server mode, if the server side times out, the client side starts throwing a bunch of errors that, after several mouse clicks to close error windows, eventually shuts down.

So two feature requests.

1) If the server dies, give 3 beeps following by a dialog that says “Server connection has been terminated, client will be terminated. Do you wish to save the current state? (yes,no)”

2) The client should give a 5 minute and 1 minute ‘warning’ if the client/server has been started with a specific time limit.

It will be very difficult to implement something that notifies the client from the server side. Often the server is simply 'killed' without warning by the queuing system. One approach is to have pvclient take an argument –time=N minutes. The client can then give a warning as time runs out. E.g. “Notice: you have X minutes left in the current session, please save your work and exit”

 This would take about 2 days.

 The Applicaition listens for AbortCheckEvent from the ProcessModule, which gets fired any connection aborts. Conseuqently, a pop up is shown giving the user an option to save the state/trace. Added command line argument --server-time; a warning is poped up 5 and 1 minutes before the timeout expires.
