I get the following been raised frequently in the windows event log on BizTalk Server 2009
The adapter "WCF-SQL" raised an error message. Details "System.InvalidOperationException: The operation is not valid for the current state of the enlistment. at System.Transactions.EnlistmentState.InternalIndoubt(InternalEnlistment enlistment) at System.Transactions.VolatileDemultiplexer.BroadcastInDoubt(VolatileEnlistmentSet& volatiles) at System.Transactions.TransactionStatePromotedIndoubt.EnterState(InternalTransaction tx) at System.Transactions.TransactionStatePromotedBase.InDoubtFromEnlistment(InternalTransaction tx) at System.Transactions.DurableEnlistmentDelegated.InDoubt(InternalEnlistment enlistment, Exception e) at System.Transactions.SinglePhaseEnlistment.InDoubt(Exception e) at System.Data.SqlClient.SqlDelegatedTransaction.SinglePhaseCommit(SinglePhaseEnlistment enlistment) at System.Transactions.TransactionStateDelegatedCommitting.EnterState(InternalTransaction tx) at System.Transactions.TransactionStateDelegated.BeginCommit(InternalTransaction tx, Boolean asyncCommit, AsyncCallback asyncCallback, Object asyncState) at System.Transactions.CommittableTransaction.Commit() at System.ServiceModel.Dispatcher.TransactionInstanceContextFacet.Complete(Transaction transaction, Exception error) at System.ServiceModel.Dispatcher.TransactionInstanceContextFacet.CompletePendingTransaction(Transaction transaction, Exception error) at System.ServiceModel.Dispatcher.TransactionRpcFacet.Complete(Exception error) at System.ServiceModel.Dispatcher.TransactionBehavior.BeforeReply(MessageRpc& rpc)

We are using a WCF-SQL adapter for generating scheduled tasks in BizTalk
Any ideas on what is causing the above?
