Duplicate query column in WDDX causes CF5 server restart
Posted by David Chandler on May 12, 2005
In CF5, if you attempt to deserialize a WDDX packet containing a recordset (query) with a duplicate column name, it will stop the ColdFusion service! You will get a message in server.log: “Unknown error threshold reached. Restarting service.” In fact, the service is not completely restarted and responds to all subsequent requests with the same error message, causing the user to see “Server busy or unable to fulfill request.”
This is a huge bug in CFWDDX. If you’re using it to store queries in the Client scope, look out!
