Thead Dump Java SE scheduled Application stuck 问题

Question

我有 java SE jar 文件在 windows 服务器上运行。应用程序处理一些记录并提交数据库中的记录，为此我正在使用 ORM 收费 eclipselink.Application 计划按时间间隔运行。我面临的问题是应用程序在运行一两天后卡住，处理是 stopped.Following 是应用程序卡住时的完整线程转储。如果有人可以阅读该转储并帮助我。

您的应用程序没有卡住。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)
        at oracle.net.ns.Packet.receive(Unknown Source)
        at oracle.net.ns.NSProtocol.connect(Unknown Source)
        at oracle.jdbc.driver.T4CConnection.connect(T4CConnection.java:706)
        at oracle.jdbc.driver.T4CConnection.logon(T4CConnection.java:228)

我宁愿检查你的数据库。
