Quota doesnot update info...

I have ISPConfig 2.2.32 on Centos, everything seem nice, but some day, i received from proftpd this warning when i upload file 30minutes.mp3:

Code:

REST 16384
350 Restarting at 16384. Send STORE or RETRIEVE to initiate transfer
STOR 30minutes.mp3
451 30minutes.mp3: Append/Restart not permitted, try again
PORT 192,168,1,126,195,123
200 PORT command successful
REST 16384
350 Restarting at 16384. Send STORE or RETRIEVE to initiate transfer
STOR 30minutes.mp3
451 30minutes.mp3: Append/Restart not permitted, try again
Transfer request completed with status: Failed, 1 SubItem(s) failed

finding, searching... i know this is quota exceed error because the log is too larger, exceed the quota of my site. i simply think, delete all unneccessary logs so that my site is smaller than the quota.... ISP statistic know that but the user+group didn't
From

Code:

repquota -avug

it shows my used user quota and group doesnot change,and i cannot FTP new data until i increase my quota for this website
I think webalizer, the statistic component of Cpanel didnot update the changes, so i try:>
/root/ispconfig/php/php /root/ispconfig/scripts/shell/webalizer.php
Output

Code:
