Aras V12SP9 Error


My Aras open instance has suddenly stopped working with this error:

After the error is dismissed the screen seems frozen and only way to quit is to close the browser.  It seems like a database issue because a different database on the same server works just fine.  Also, I migrated the problem database to a different computer and it suffers from the same issue.

Any pointer from Aras experts out there is highly appreciated.
