SqlServer 存储过程 多个with as公共表达式 查不出结果 假死

发现SqlServer的一个奇怪问题,有一个存储过程,用了多个With as的公共表达式,运行一段时间后,从应用程序连接这个存储过程就查不出结果,提示查询超时。若把应用程序中的那句Sql直接放到SqlServer中运行能很快查出结果。当应用程序查不出结果时,再把这个存储过程重新运行,应用程序就立马能查出结果。仿佛重新运行存储过程,就释放了一些东西。这是为什么?
存储过程如下:
ALTER PROCEDURE [dbo].[PR_FIN_EmployeeCommission]
@DeptFullCode nvarchar(100)=null,
@StartDate date='2012-10-01',
@EndDate date='2012-10-31',

@Trade nvarchar(50)='',
@Estate nvarchar(50)='',
@EmpID nvarchar(50)='',
@RoleName nvarchar(50)='',
@ContractStartDate date='2012-10-01',
@ContractEndDate date='2012-10-31'
