Apache tomcat 6问题

我开发了一个在Apache Tomcat 6服务器上运行的应用程序。为了开发这个应用程序，我使用了Struts 2.0和Hibernate 3.0。我面临的问题是每当我启动我的tomcat服务器时，我的应用程序运行正常，但如果我不使用它超过12小时，应用程序会抛出一些异常和500错误，但如果我再次重新启动服务器它运行没有任何问题。有人能告诉我这里有什么问题，为什么如果我不使用它12小时，应用程序崩溃。Apache tomcat 6问题

这是例外

和异常/错误消息是？ –

你能添加异常吗？ – bstick12

我想你应该仔细看看卡塔利娜日志。这可能是内存泄漏的情况。 –

这错误通常是一个陈旧的JDBC连接的结果。查看数据库连接池（DBCP）。请参阅此处的数据源部分link

尝试在您的数据源中使用以下属性，以保持连接的活动时间足够长以防止出现错误。

maxActive = 50 
maxIdle = 25 
minIdle = 5 
initialSize = 5 
minEvictableIdleTimeMillis = 60000 
timeBetweenEvictionRunsMillis = 60000 
maxWait = 10000 
validationQuery = "/* ping */"

但我必须这样做？ – Abhisek

你看过那个链接吗？ – gotomanners

如果没有更多的细节，就很难给出准确的答案，但是这个问题通常会在过时的连接中出现。您是否在应用程序中使用连接池？如果是，在使用前是否验证连接？

您正在使用休眠配置文件吗？看看这个问题：http://stackoverflow.com/questions/730827/hibernate-c3p0-mysql-broken-pipe –
