SSMS 2012 System.OutOfMemoryException(客户端)和SQL提示符(调试信息包含)

Question

一些背景:我在SSMS 2012中遇到了这个内存异常,因为它与Red Gate的SQLPrompt一起发布(这个例外在同一台笔记本电脑上的SSMS 2008R2中从未发生).

我最初每天都遇到这些异常(SSMS2012和SQLPrompt),这迫使我关闭并重新打开SSMS(以及我正在处理的所有事情).几个月前,我偶然发现了一个支持线程,指出可能的附加组件是原因所以我卸载了我唯一的附加组件(SQL Prompt,但没有卸载开发人员的其他软件包)并且花了很多个月没有一个例外减去System.OutOfMemoryException异常.

一旦SP1在2012年发布,我就应用它并重新安装SQL Prompt(最新版本),看看问题是否已经解决,并且在开发时间的7小时内,我再次受到了臭名昭着的System.OutOfMemoryException的欢迎.

通过所有这些,我一直在打开Red Gate的门票,并在他们看到异常时提交调试日志,但由于内存异常没有明确列出SQLPrompt,他们不会将问题上报给开发团队.在此特定异常之前,SQL Prompt在SSMS 2012 IDE(Visual Studio 2010)中抛出了许多异常(下面列出了一些异常).我相信内存异常是SQL Prompt如何管理缓存数据并占用SSMS可用内存的问题的症状,最终会导致异常.

我已经学会了如何推迟这个问题以及如何重现它,它与两个变量直接相关:

1. 在SSMS(对象资源管理器和查询窗口)中连接和处理多个实例.即连接到7个实例在2-3小时内净化了异常.
2. 从多个实例返回结果集.这包括SSMS用于将信息返回到IDE以及返回到各个查询窗口的结果的查询.

我连接到越快的异常的实例越多,这导致SQL Prompt缓存每个实例的所有对象信息.一旦引发内存异常,情况就会降低,直到SSMS完全崩溃(除非我先关闭它).

我所追求的是如何收集更多/更好的信息,以提交给红门以纠正这个问题.这是我需要你帮助的地方.

以下是SQL Prompt引起的一些异常:

这是内存异常:

.BatchParser.ThunkCommandExecuter.ProcessBatch(N/A,N/A,N/A)

同样,要清楚,我不知道其他异常是否相关,但内存异常仅在安装了SQL Prompt时发生.

谢谢你的协助!
