我对事务锁定有一个奇怪的问题，我无法指出问题的来源。
我们的客户报告他们无法使用系统的一个页面，而且它已超时。该页面执行一个存储过程，其中包含CTE但根本没有事务。请参阅下面的存储过程：
ALTER PROCEDURE [dbo].[X_WMS_GET_SALESORDERS_CUSTOM]

@FromDueDate DateTime= NULL,
@ToDueDate DateTime = NULL,
@SearchTerm VARCHAR(200) = NULL,
-- Dynamic filters
-- * Display name will be the parameter name without the @FILTER_ and underscores(_) are replaced by white space( ).
-- * BIT datatype is the equivalent of boolean or char(1) 'Y' or 'N'. This will display a Yes/No dropdown selection on UI.
@FILTER_Order_Date_from DATETIME = NULL,
@FILTER_Order_Date_to DATETIME = NULL,
@FILTER_Account VARCHAR(200) = NULL,
@FILTER_Locked BIT = NULL,
@FILTER_Stocks_Ready BIT = NULL,

当页面仍然关闭时，我尝试在SQL Management上手动运行存储过程，并在1或2秒内执行，没有任何问题。我正在使用ASP.Net MVC来显示此存储过程的结果。
我重新启动了服务器，但问题仍然存在。我能够解决它的唯一方法是修改存储过程中的任何行执行它并撤消更改并再次执行然后它会神奇地解决问题。
有没有人遇到过这个？任何帮助将不胜感激，因为我要求明天报告刚刚发生的事情，我需要在会议上说些什么:(
TIA
