Capping issues with voucher system

[Daren Hendricks]

Hi,

We experiencing a strange situation. We have a voucher system using
freeradius  and some customers are being capped when they reach their
voucher limit. Some customers though seem to continue to use about
100-300MB over before they eventually get capped.

Has anybody experienced anything like this before? Any pointers on where
the possible issues might be or where to look to start diagnosing?

Thanks,
Daren
