Sudden termination of NoMachine virtual desktops when Kerberos tickets are renewed

A NoMachine virtual desktop suddenly terminates each time the Kerberos ticket renewal is requested.

By default, NoMachine is configured to renew Kerberos tickets every ten minutes: the session will work normally for ten minutes and then it will terminate. 

A possible workaround is to set a high value in the KerberosCredentialsRenewal key in the node.cfg file, so that the ticket renewal will not occur during the life of the session. Value set in the KerberosCredentialsRenewal key must be lower than the maximum lifetime set on the system for Kerberos credentials.

This problems affects NoMachine servers v. 6.4.6.
