quotas problem on 4.11/UFS

[Nicolas KOWALSKI]

Hello,

Our FreeBSD 4.11 fileserver (NFS, Samba) seems to have some problems
with quotas, apparently just after a lot of files are deleted. The
clients are mostly Linux 2.6 workstations (75), and some Windows XP
(10).

For example, yesterday the quota files of one disk were these:

-rw-r-----  1 root tty 2097120 Mar 21 23:14 quota.group
-rw-r-----  1 root tty 2097120 Mar 21 23:14 quota.user


But today, after a user deleted a lot of his files, the quotas files
are:

-rw-r-----  1 root tty    2097120 Mar 22 23:10 quota.group
-rw-r-----  1 root tty 4294967264 Mar 22 23:10 quota.user


The repquota command still works, but takes more time (30 secs instead
of immediate).

We will reboot the server today to rebuild the quota files.

Does anyone know what is happenning here, and if possible how to
prevent it ? Thanks.
