这是我的情况。我有一个应用程序在我的客户端 24/7 的 2 台服务器上运行：
应用服务器：TomCat + JBOSS 5 数据库服务器：SQL Server 2008 R2
最近我遇到一个错误，每周四早上 6 点我的 JBOSS 都会遇到这个错误：

我的应用服务给出了这个错误：
javax.ejb.EJBException: com.microsoft.sqlserver.jdbc.SQLServerException: Connection reset by peer: socket write error; nested exception is: com.microsoft.sqlserver.jdbc.SQLServerException: Connection reset by peer: socket write error: com.microsoft.sqlserver.jdbc.SQLServerException: Connection reset by peer: socket write error; nested exception is: com.microsoft.sqlserver.jdbc.SQLServerException: Connection reset by peer: socket write error: Connection reset by peer: socket write error
我的客户声称周四早上 6 点在 DB 和 Apps 服务器上没有进行任何活动，因此我不知道是什么触发了这个错误。它只在每周四早上 6 点发生。任何帮助我都会非常感激！
