Hello, This is my first post to the tomcat forum, so please excuse of any errors.
I am looking at a fix for one of the bug (bug id#53267) in Catalina. Ref - https://issues.apache.org/bugzilla/show_bug.cgi?id=53267 The bug is in RESOLVED FIXED state. As per this bug, the one hr time interval (when a GC event is kicked off) was changed to Long.MAX ( a very long time). It is also mentioned the value is configurable using a system property - org.apache.catalina.core.jreMemoryLeakPreventionGCDaemonPeriod. When I tried setting this property to 3600000, assuming a full GC will be kicked every hour it did not happen. Curious, I looked into the code for version 7.0.47, that config variable was not used in org.apache.catalina.core.JreMemoryLeakPreventionListener. Code snippet from JreMemoryLeakPreventionListener in tomcat version 7.0.47 : Class<?> clazz = Class.forName("sun.misc.GC"); Method method = clazz.getDeclaredMethod( "requestLatency", new Class[] {long.class}); method.invoke(null, Long.valueOf(Long.MAX_VALUE - 1)); Instead of using the Long.MAX_VALUE-1 by default, it should try and resolve if from the aforementioned system property. Am I wrong to assume the config variable will be present in 7.0.47? Thanks for your time, and my sincere apologies if I had wasted it. -- Bharath.
