I have a 5TB NSS volume on which I'd like to give all my users 10GB of
space. I'm using iManager 2.6 with the Storage Management
plugins to try to set quotas for the users, about 100 at a time.

Somewhere around user# 700 or so, it breaks and I get a "Could not get
volume user restriction information" when I click on "User Quotas" for this
volume in iManager.

I've used NSS volumes on OES Linux before without any problems, but this is
the first time I've tried to use quotas. Am I doing something wrong, or is
their some upper limit that I'm hitting? We have NSS volumes on Netware with
3-4K user space restrictions without any problem.
