出现这个问题的原因是tomcat 7的一个默认配置(JreMemoryLeakPreventionListener) 方法一：可以在JVM启动参数中加入-XX:+DisableExplicitGC来禁止System.gc()。当然这个方法不太好，你也可以用另一种方法： 方法二： 在html中： Thank you Konstantin and Chris for your attention. As stated in the initial post:'We have recently deployed tomcat-6.0.28 in our organization and arenoticing every hour, a Full GC is occurring. The same application,same JVM, same JVM args, just a new tomcat release.' Using the default JreMemoryLeakPreventionListener configuration thathas 'gcDaemonProtection=true' will result in 1hr FullGCs using Sun1.6 b18, b20 and b21on Solaris and Windows. We've tested andsuccessfully 'contained' the FullGC behavior using one of the belowconfigurations: 1) suppress the FullGC using JVM arg -XX:+DisableExplicitGC 2) keep the FullGC but to defer to the CMS collector using JVM arg-XX:+ExplicitGCInvokesConcurrent 3) gcDaemonProtection="false"/> 4) Disable the listener altogether We've decided to go with option 3.
