打开SQL连接时出现算术溢出异常

Question

ArithmeticOverflowException打开与底层SQL数据库的SQL连接时,我非常奇怪(下面包含堆栈跟踪).使用哪个版本的服务器并没有什么区别(我已经验证了MS SQL 2005/2008/2012/2014),错误仍然是相同的.安装了Windows Update的所有最新更新和修补程序.操作系统是Windows 8.1/10(两个系统都相同).服务器在本地安装,并通过用户和密码建立连接.连接超时验证范围为15到1000秒.

最令人惊讶的是应用程序工作正常,并与服务器正常通信,执行许多不同的查询,但突然发生此异常.我注意到这个异常在一些Windows更新后开始显示(不知道哪一个).

我查看了.NET代码,但不知道是什么原因会导致算术溢出异常......

我有同样的问题.Lavasoft也是一个原因.如果有任何Lavasoft程序,我检查了程序和功能,我很惊讶地找到了名为Lavasoft的WebCompanion的应用程序.我还发现了一个正在运行的服务LavasoftTcpService.

1. 我停止了LavasoftTcpService服务(来自services.msc)
2. 我从程序和功能中卸载了WebCompanion.
3. 上面提到的两个dll(LavasoftTcpService.dll和LavasoftTcpService64.dll在C:\ Windows\System32和C:\ Windows\SysWOW64中)仍然存在.我改名了,问题消失了.

在这些步骤之前,我尝试仅更改dll名称,并且解决localhost存在问题:而不是127.0.0.1系统正在寻找0.0.0.0.Ping给了我一条错误消息"Ping请求找不到主机localhost.请检查名称然后重试"

3个步骤解决了这个问题.

我们有同样的问题,它是由LavasoftTcpService64.dll.摆脱这个并不容易,解决了这个问题.检查其存在以下文件夹:C:\Windows,C:\Windows\System32和C:\Windows\SysWOW64.
