The Check Interval value in your General Preferences controls the interval in minutes between checks for the license time-out feature. If Softimage has been completely idle since the last check, it temporarily stops communicating with the license server. When activity resumes, Softimage starts communicating again.
If there has been no communication for a certain period of time (configured on the server), the server reclaims the license and makes it available for other users.
If the license has been lost when activity resumes, Softimage attempts to get another license from the server. If none are available, you are given an opportunity to save your work before exiting.
Softimage is not considered idle if there been any mouse or keyboard interaction, command or script running, or progress bar during the last check interval. Softimage is never idle in batch mode.
To disable the license time-out feature, set this value to 0.
