Set your Acct-Interim-Interval to something low (say 300 seconds) and 
amend your SQL check for Simultaneous-Use so that it ignores stale data 
that has not been updated in more than 900 seconds (a value three times 
larger than Acct-Interim-Interval).

You need to have serious words with your NAS vendor why you are not 
seeing accounting on-off packets (your NAS will send a 'reset' 
accounting packet to your RADIUS server that you can use to trigger an 
early session stop for all the users).
