quota problems (again)

[Luca Ferrari <fluca1978@katamail.com>]

Hi,
it happened again: quota is saying that a user has exceeded the granted space 
while I cannot find files that do it. Allow me to proceed in order:

mammuth:~# quota -u alonso
Disk quotas for user alonso (uid 2220):
     Filesystem  blocks   quota   limit   grace   files   quota   limit   
grace
      /dev/hda5 4021252*  10000   12000            2879       0       0

The quota is applied to the /dev/hda5 partition only, that includes /tmp 
directory. I've run the following command:

find / -uid 2220 >quota.txt  

of course having a check on the user id (2220) in the /etc/passwd file. The 
file has reported that the user owns files only a few directories, and a du 
-hs on those directories gave to me a total amount of 8 MB, less than the 10 
of quota roof. Furthermore, quota gives a 2879 files owned by the user, while 
executing
cat quota.txt | wc -l 
gives a 1519 that is the about the half!

I've tried with a quotacheck over the partition, but the situation remains the 
same. What can be? Any idea?

Thanks,
Luca
