Secure Global Desktop 4.40 Administration Guide > Applications, Documents, and Application Servers > Applications Disappear After About Two Minutes
If users find that their applications disappear unexpectedly after about two minutes, it might be that a proxy server is timing out the connections. Proxy servers drop a connection after a short period of time if there is no activity on the connection.

Alternatively, use the following command:
$ tarantella config edit --sessions-aipkeepalive secs
