First chance exception at $763FC632. Exception class EMSSQLNativeException with message '[FireDAC][Phys][ODBC][Microsoft][SQL Server Native Client 10.0]Connection is busy with results for another command'. Process DS服务器.exe (6424)

解决方法SQLserver升级到SQL2008  SQL Server Native Client 10.0不能同时连接SQLserver2000数据库。
