Connection timeout [1]

Hi!
Help me plz with the question:
When I use Xmanager to connect Solaris server, I can lost connection if a network ploblem occur and the server is not accessible for some minutes.
Can I set any parameter of Xmanager to change or cancel this timeout for close the connection?

It may take awhile for the remote server to clean up the processes after an unsuccessful log off. It may take up to few minutes for slow machines. This process cannot be intervened by remote users.

Hope this helps.
