Hi, Tomcat Version 5.5.27 OS: Linux Red Hat Linux 5.3 Enterprise 64bit
I have a tomcat server setup, with the following configuration added: -XX:+UseLargePages -Xms14336m -Xmx14336m -XX:NewRatio=4 -XX:MaxPermSize=256m -XX:+UseConcMarkSweepGC -XX:CMSInitiatingOccupancyFraction=51 -XX:+CMSIncrementalMode -XX:+CMSIncrementalPacing -XX:CMSIncrementalDutyCycle=75 -XX:CMSIncrementalDutyCycleMin=20 -XX:CMSIncrementalSafetyFactor=10 -XX:CMSIncrementalOffset=0 -XX:CMSExpAvgFactor=25 When I check the JVM output via jConsole the Eden space only has an available max space of 10496kbytes, I believe that my configuration of -(XX:NewRatio=4) should effectively set this parameter to 20% of the total available heap (-Xmx14336m) - should be approx 2936000kbytes. This problem, creates an issue that the Eden space GC runs frequently, and the time available between these minor GC's is to short for the Tenured space to be effectively collected. Any Help or suggestions would be greatly appreciated. Thank You, -- Mitchell Smith The information contained in this email (and any attachments) is confidential and may be privileged.
