radius+que+user limit what is the problem

Hey!

Im using mikrotik 2.9x and freeradius older and newest...... Everything is good, bandwidth and traffic limitations too.... only trouble is when i add to user e.g. 5 GB upload and 5GB download limit... when user login mikrotik only register 4 GB limit 4096 mb and not more! So I cant add 15GB for download for example … and it is very big problem for me! I can`t find any help why it is???

If i add 15 GB limit in mikrotik local user it is working fine… but if I`m using radius do nothing only send 4GB limit to mikrotik…

Dows have any idea about it??? Can somebody help me???

Thanks,
Sorry for my english!
