Hello, We have recently deployed tomcat-6.0.28 in our organization and are noticing every hour, a Full GC is occurring. The same application, same JVM, same JVM args, just a new tomcat release.
I have addressed the issue by adjusting the server.xml and disabling gcDaemonProtection. <Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener" gcDaemonProtection="false"/> Ideas on what is causing the Full GC and why every hour? our environment: tomcat-6.0.28 java.vm.specification.vendor:Sun Microsystems Inc. java.runtime.version:1.6.0_18-b07 sun.arch.data.model:64 os.version:5.10 os.arch:sparcv9 GC.log 212621.426: [Full GC (System) 212621.427: [CMS:81164K->68018K(8005248K), 4.0688219 secs] 240526K->68018K(8350272K),[CMS Perm : 91877K->91830K(131072K)], 4.0694842 secs] [Times:user=4.08 sys=0.01, real=4.07 secs] 216225.566: [Full GC (System) 216225.567: [CMS:82629K->64655K(8005248K), 3.9778052 secs] 210097K->64655K(8350272K),[CMS Perm : 91874K->91837K(131072K)], 3.9784728 secs] [Times: user=3.98 sys=0.00, real=3.98 secs] 219829.596: [Full GC (System) 219829.597: [CMS:87605K->73336K(8005248K), 4.2279768 secs] 313716K->73336K(8350272K),[CMS Perm : 91930K->91841K(131072K)], 4.2286745 secs] [Times: user=4.23 sys=0.00, real=4.23 secs] Thanks, Donnie --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
