CentOS 5.3 quota

I am running on CentOS 5.3 x86 64bit.

I setup quotas on /home as I thought successfully, I tested numerous times with a couple of different users. I login this morning and find my /home near 100% wondering what happened.

I have one user that some how blew through his 3.5 gig quota and uploaded 14 gigs of data. Initially when I went to go look at his quota, it reported being under his quota.

So I ran quotacheck which gave me this message:
[root@www home]# quotacheck /dev/VolGroup00/LogVol01
quotacheck: Quota for users is enabled on mountpoint /home so quotacheck might damage the file.
Please turn quotas off or use -f to force checking.

I then ran "quotacheck -f /dev/VolGroup00/LogVol01", which then updated the users quota information and now he is over the limit and can't write any more files.

I've read that you should run quotacheck in cron, but just running the command without the -f will make the server spit out that message and will not do a regular quotacheck which concerns me.

The way I tested this, I placed a few files out there that went over the limit and at the time it told me that I was over the limit. Is there anything that I am doing incorrectly or things that I could check to make sure I don't have this problem creep up again where the user blows through his quota?

REPQUOTA(8)						    BSD System Manager's Manual 					       REPQUOTA(8)

NAME

     repquota -- summarize quotas for a file system

SYNOPSIS

     repquota [-g] [-u] [-v] filesystem ...
     repquota [-g] [-u] [-v] -a

DESCRIPTION

     Repquota prints a summary of the disk usage and quotas for the specified file systems.

     Available options:

     -a      Print the quotas of all the filesystems configured with a quota mount option file at its root.

     -g      Print only group quotas (the default is to print both group and user quotas if they exist).

     -u      Print only user quotas (the default is to print both group and user quotas if they exist).

     -v      Print a header line before printing each filesystem quotas.

     For each user or group, the current number of files and amount of space (in kilobytes) is printed, along with any quotas created with
     edquota(8).

     Only members of the operator group or the super-user may use this command.

FILES

     Each of the following quota files is located at the root of the mounted filesystem.  The mount option files are empty files whose existence
     indicates that quotas are to be enabled for that filesystem.

     .quota.user       data file containing user quotas
     .quota.group      data file containing group quotas
     .quota.ops.user   mount option file used to enable user quotas
     .quota.ops.group  mount option file used to enable group quotas

SEE ALSO

     quota(1), quotactl(2), edquota(8), quotacheck(8), quotaon(8)

DIAGNOSTICS

     Various messages about inaccessible files; self-explanatory.

HISTORY

     The repquota command appeared in 4.2BSD.
