Need your valuable suggestion on my Sharepoint 2010 site quotas and lock issue. Not sure how the site collection changing from "No Lock" status to "Read Only", How to audit or find out. checked so far: No local disk Space Issue, Quota limit not full, SQL db Server space is enough, backups successfully running but still it's changing to Read only, Nothing into the event logs & ULS Logs.
Find the info from IIS logs but which is recording the a/c name like who is reverting the changes(i.e.. Read Only to No Lock).. but i would like to track which a/c initially changing from No lock to Read only(which i cant find in ULS logs). Appreciate your suggestions.
