Did you do 'quotacheck -avug' ?

I've used kernel 2.2.11 with RAID1 (08241999) to mirror the partition
/var/spool with quota. Btw, I got about 4,500 users with quota and there
seems to be a problem with quota implementation in the 2.2.x kernels, my
experience is I'm getting high load average, even if I have lots of
idle CPU and memory -- there seems to be a block in I/O, 'ps' reports
status 'D' on those blocked processes and I have to reboot.
There's a major patch for the quota code itself in 2.2.11 and a few lines
in 2.2.12.
So if you're concerned with stability, better use the old kernel
series (2.0.x), I use 2.0.38.
