We have our SP 2010 site collection configured with the following quota template settings:
- Unchecked: Limit site storage
- Unchecked: Send warning email when site storage reaches...
- Sandboxed Solutions Resources Quota: 999999 points
- Unchecked: Send warning email when usages per day...
Even with these settings in place, every Monday, the storage quota seems to be "met" and SharePoint automatically locks the site collection (making it read-only). So we go in and unlock it, and we're good for another week.
We have basically zero physical storage limitations, both on the database and filesystem side.
I looked in the Storage Metrics section of Site Settings for the top-level site collection, and I can see the sub-sites that are using "a lot" of storage (one uses 1.8GB, the other about 1GB). The "% of Site Quota" column reads "Not Available" for all rows in this report.
We have no need for quotas and we absolutely do not want this locking to keep happening. Is there a way to stop it?
Was not actually the quota locking the site -- see comments below accepted answer.
