We received a bunch of messages in the K2 server log saying:


"2516","2007-11-30 07:08:27","Error","General","4129","DBException","SqlConnection* K2Sql::RollbackTransaction","4129 A database error occured : There is already an open DataReader associated with this Command which must be closed first.    at System.Data.SqlClient.SqlInternalConnectionTds.ValidateConnectionForExecute(SqlCommand command)
   at System.Data.SqlClient.SqlInternalTransaction.Rollback()
   at System.Data.SqlClient.SqlTransaction.Rollback()
   at K2Sql.RollbackTransaction(SqlTransaction st)","4a29419ab19c405cabd26885650bfa3f",""


 Any idea what this might mean?

    For DataReader, if you called Commmand.executeReader() in the same command without execute dataReader.Close() first, you will get that error message, "There is already an open DataReader associated with this Command which must be closed first.".
