2013-10-18 9:50:26 org.apache.catalina.core.StandardContext reload
信息: Reloading Context with name [/SzcaAc] has started
2013-10-18 9:50:26 org.apache.catalina.core.ApplicationContext log
信息: Closing Spring root WebApplicationContext
2013-10-18 9:50:26 org.hibernate.impl.SessionFactoryImpl close

2013-10-18 9:50:26 org.apache.catalina.loader.WebappClassLoader clearReferencesJdbc
严重: The web application [/SzcaAc] registered the JDBC driver [com.mysql.jdbc.Driver] but failed to unregister it when the web application was stopped. To prevent a memory leak, the JDBC Driver has been forcibly unregistered.
2013-10-18 9:50:26 org.apache.catalina.loader.WebappClassLoader clearReferencesThreads
严重: The web application [/SzcaAc] appears to have started a thread named [Thread-30] but has failed to stop it. This is very likely to create a memory leak.
2013-10-18 9:50:26 org.apache.catalina.loader.WebappClassLoader clearReferencesThreads
严重: The web application [/SzcaAc] appears to have started a thread named [Timer-7] but has failed to stop it. This is very likely to create a memory leak.
2013-10-18 9:50:26 org.apache.catalina.loader.WebappClassLoader clearReferencesThreads
严重: The web application [/SzcaAc] appears to have started a thread named [Timer-8] but has failed to stop it. This is very likely to create a memory leak.
2013-10-18 9:50:26 org.apache.catalina.loader.WebappClassLoader checkThreadLocalMapForLeaks
严重: The web application [/SzcaAc] created a ThreadLocal with key of type [com.sun.faces.util.Util$1] (value [com.sun.faces.util.Util$1@395294]) and a value of type [java.util.HashMap] (value [{com.sun.faces.patternCache={ = }}]) but failed to remove it when the web application was stopped. Threads are going to be renewed over time to try and avoid a probable memory leak.
2013-10-18 9:50:26 org.apache.catalina.loader.WebappClassLoader checkThreadLocalMapForLeaks
严重: The web application [/SzcaAc] created a ThreadLocal with key of type [java.lang.ThreadLocal] (value [java.lang.ThreadLocal@15c9cb8]) and a value of type [com.opensymphony.xwork2.inject.ContainerImpl] (value [com.opensymphony.xwork2.inject.ContainerImpl@1350d59]) but failed to remove it when the web application was stopped. Threads are going to be renewed over time to try and avoid a probable memory leak.

项目有一个定时任务，在项目启动的时候执行，之后每四小时执行一次，现在的情况是启动时执行完成后，项目又重新执行，不知道何故？请大家帮忙看看，谢谢！

你的定时任务用的什么方案？
