Request Servertoontown Offline Servers

The Toontown Test Server or known as Test Town or simply Test was a server hosted by Disney for testing new content for Disney's Toontown Online with a small amount of players before making the content publicly available on the 'open' server. Only subscribing players who had requested (and subsequently granted) access through the website could participate on the test server. Verify the status of the database server. If the problem persists, contact Technical Support. A review of the deadlocks shows a stored procedure of dbo.spUnpublishPolicyRequest being executed with an objectlock against the dbo.POLICYREQUESTACTIONSERVERS table from each of the locks.

Summary: Runbook Server <computer> is experiencing frequent errors while accessing the database
Details: The Runbook Server is experiencing frequent errors while accessing the database. Verify the status of the database server. If the problem persists, contact Technical Support.

A review of the deadlocks shows a stored procedure of dbo.sp_UnpublishPolicyRequest being executed with an objectlock against the dbo.POLICY_REQUEST_ACTION_SERVERS table from each of the locks.

Cause

Toontown Servers To Play

Numerous runbook instances are being completed at the same time and executing the dbo.sp_UnpublishPolicyRequest stored procedure to remove the completed instance. The foreign key relationship from the dbo.POLICY_REQUEST_ACTION_SERVERS table with a cascading delete option but no index against the SeqNumber column of the foreign key is causing a full table lock to occur rather than a more selective row lock. When the multiple executions attempt to convert their intent to lock (IX) locks to exclusive (X) locks, the deadlock results.
