java - 线程转储 Java SE 计划应用程序卡住问题

Question

我有在 Windows 服务器上运行的 java SE jar 文件。应用程序处理一些记录并将记录提交到数据库上，为此我正在使用 ORM toll eclipselink。应用程序计划定期运行。我面临的问题是应用程序在运行一两天后卡住并且处理停止。以下是应用程序卡住时的完整线程转储。如果有人能读到那个转储并帮助我。

您的应用程序中没有任何内容被卡住。您的应用程序线程pool-1-thread-1实际上正忙于查询您的数据库:

java.lang.Thread.State: RUNNABLE
        at java.net.SocketInputStream.socketRead0(Native Method)
        at java.net.SocketInputStream.read(Unknown Source)
        at java.net.SocketInputStream.read(Unknown Source)

我宁愿检查你的数据库。
