When we attempt to update or add permissions to any page, we are suddenly receiving the following error (and the operation fails):

Error: is currently unavailable.

Any suggestions? The database seems fine. The site is moving quickly other than this. I updated stats and reindexed the tab table. I'm out of ideas.

most likely there is a performance issue with the database, usually caused by large tables.
Please check the number of records in ScheduleHistory, Eventlog and Exceptions tables.

We've purged the schedule history and event log. There's 800 records in the exceptions table. I've reindexed the entire database and updated statistics and the issue remains. This is in the event log when I try to update permission on a page, followed by the error above:

Message:Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.

I can't help but wonder if its somehow passing a parameter that SQL is having trouble processing, but I don't have admin rights on the server and can't run profiler to look. Do you have any other suggestions?
