We start tomcat at 09:42, but at 11:35, tomcat pause temporarily, then it reinit the ApplicationContext. detail logs: ... custom thread:dts.executeTasks [2014-09-18 11:35:52,493] [6888141] INFO - com.jd.clover.center.service.AbstractScheduleTaskProcess::call - 执行任务[com.jd.clover.center.service.AbstractScheduleTaskProcess$1],条数:1成功! http-8010-1 [2014-09-18 11:35:52,493] [6888141] INFO - com.jd.clover.center.service.AbstractScheduleTaskProcess::execute - 执行任务[com.jd.wms.location.clover.LocationBackSendOtm][0/1]完成.... 2014-9-18 11:35:52 org.apache.coyote.http11.Http11Protocol pause 信息: Pausing Coyote HTTP/1.1 on http-8010 2014-9-18 11:35:53 org.apache.catalina.core.AprLifecycleListener init 信息: The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: /usr/local/lib 2014-9-18 11:35:53 org.apache.coyote.http11.Http11Protocol init 信息: Initializing Coyote HTTP/1.1 on http-8010 2014-9-18 11:35:53 org.apache.catalina.startup.Catalina load 信息: Initialization processed in 514 ms 2014-9-18 11:35:53 org.apache.catalina.core.StandardService start 信息: Starting service Catalina 2014-9-18 11:35:53 org.apache.catalina.core.StandardEngine start 信息: Starting Servlet Engine: Apache Tomcat/6.0.33 2014-9-18 11:35:53 org.apache.catalina.startup.HostConfig deployDescriptor 信息: Deploying configuration descriptor ROOT.xml 2014-9-18 11:35:54 org.apache.catalina.loader.WebappClassLoader validateJarFile 信息: validateJarFile(/export/App/pickingplan.wms5.jd.local/WEB-INF/lib/servlet-api-2.4.jar) - jar not loaded.
