I'm having the same issue. When DDDAUDIT runs, it generates a "Success" message that is inserted into PS_MESSAGE_LOG upon success. However, because these "Invalid server name" messages have already been inserted without using the PRCSAPI.sqc methods, the counter PRCSAPI uses to counte the sequence number for the message does not match what is in the database. PRCSAPI thinks it is on SEQNUM 1, when in fact it should be on SEQNUM 23. I cannot track down where this message is being thrown or why it is finding a server that has been deleted. I suspect orphaned data but for the life of me I cannot locate it.
