Why does I-Tunes log me out after 15min of play?

Question

I've got 2 profiles set up on the mac, and when the non admin profile is logged in, when i-tunes is running, after 15mins of playback, the profile logs itself out...
i've checked and the mac has been set to never go to sleep, the screen saver is not due to come on at all and the display has been told never to go to sleep.
any suggestions?

Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
In the Console window, look under the heading DIAGNOSTIC AND USAGE INFORMATION on the left for crash or panic reports. If you don't see that heading, select
View ▹ Show Log List
from the menu bar.
A crash report has a name that begins with the name of the crashed process and ends in ".crash". It may be under either of the two subcategories, "System" and "User." A panic report has a name that begins with "Kernel" and ends in ".panic".
Select the most recent of each and post the entire contents — the text, please, not a screenshot. In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.)
Please don’t post any other kind of diagnostic report, such as a hang log — they're very long and not helpful.
