Question

我们遇到了一个问题,如下所示,我们不知道问题是:1.从数据库读取的时间太短到达StuckThreadMaxTime 600s 2.database查询运行时间过长2.锁定数据库或其他对象

任何建议将不胜感激!

线程转储显示线程在从SQL Server接收数据时卡住了超过600秒(10分钟).

根据我的经验,这可能是长时间运行的数据库查询,也可能是Weblogic与数据库之间的间歇性连接故障,使得套接字处于不稳定状态.

这是一次性还是相同的堆栈跟踪也可用于其他卡住的线程 - 在同一行？如果是,那么您可能需要使用SQL查询分析器查看数据库查询,或者它在MS-SQL中等效

如果它是一次性的,它可能是网络问题
