Andy, just to add to CCIE19999's points,
"exec-timeout" is for INCOMING sessions to your router and
"session-timeout" is for OUTGOING sessions from your router. With that
said, you need to check if you are being disconnected due to
"absolute-timeout", "session-timeout, " or " exec-timeout" either
locally or from remote site.
