Good afternoon. We run a portal solution on top of Tomcat 6.0.16 (and Java 1_5_16). We are running out of PermGen space for several instances of tomcat, which I believe could be some bad code we've received from our development team. To test a theory, I'd like to expand the size of our PermGen memory space from the 64m default to 128m (and possibly higher). I know by increasing this setting, I could just be delaying the inevitable. I am running Lambda Probe (LP), allowing me to see the various memory allocations and I see (as well in the logs), PermGen cap out and then continuous GC occurring. I have a 2-part question. 1. In Tomcat6w.exe, I set one java_opt to include -XX:MaxPermGen=128m, but the tomcat service then does not start up. When I change it to be -DXX:MaxPermGen=128m (like a lot of our other settings , it starts up just fine. Yet.. Lambda probe still shows that I only have a 64m cap on PermGen. Am I setting this properly? (everything I read says yes, but I'm not getting confirmation via LP). 2. How can I verify PermGen max size has been increased other than using Lambda probe (to keep LP honest). Below are all the java_opts I currently have set. Some are specific to the portal environment we run. -Dcatalina.home=E:\apache\Tomcat6 -Dcatalina.base=E:\apache\Tomcat6 -Djava.endorsed.dirs=E:\apache\Tomcat6\common\endorsed -Djava.io.tmpdir=E:\apache\Tomcat6\temp -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djava.util.logging.config.file=E:\apache\Tomcat6\conf\logging.propertie s -Dcom.vignette.workingDir=E:\Vignette\cds\inst-vgninst\vcm-vgninst\cdsvc s\stage-prod\cds-prod\as\conf -Dcom.vignette.portal.installdir.path=C:\Vignette\Portal -Dcom.sun.management.jmxremote -DXX:MaxPermGen=256m For perspective, I am an administrator, not a developer.
