Subject PS Old Gen filling up...
Date Wed, 12 Jul 2006 14:23:40 GMT
Hi All,

 

Got a situation here where PS Old Gen within the JVM heap is gradually
filling up and locking to a point where GC will not release any of it and
the application hangs.

 

Running Tomcat 5.5.15 and SUN JDK 1.5_07.

 

Machine is an 8GB dual Xeon processor Dell 2850.

 

The JVM options are set as follows;

 

-Dcatalina.home=F:\tomcat5

-Dcatalina.base=F:\tomcat5

-Djava.endorsed.dirs=F:\tomcat5\common\endorsed

-Djava.io.tmpdir=F:\tomcat5\temp

-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager

-Djava.util.logging.config.file=F:\tomcat5\conf\logging.properties

-Duser.language=en

-Duser.country=GB

-Xms1330m

-Xmx1330m

-XX:+UseParallelGC

-XX:ParallelGCThreads=2

-XX:+UseParallelOldGC

-XX:+UseAdaptiveSizePolicy

-XX:NewSize=400m

-XX:MaxNewSize=400m

-XX:PermSize=128m

-XX:MaxPermSize=128m

 

Has anyone had similar behaviour or can you point me in the right direction?

 

Thanks in advance.

 

Darren Kukulka
