Also dropping the parameter -XX:MaxNewSize=256 helps with big JVM’s. We had an big speedup when removing that parameters as it was limiting the tomcat-container from fully using the larger amounts of memory.

Hello,
I'm currently having a problem with taskomatic. while is trying to generate the reporsitory metadata for my repository 'rh6-x86_64-os' I'm getting the following error:

I have extended the memory parameter in the /etc/sysconfig/tomcat file from 256 to 1024
JAVA_OPTS="-ea -Xms1024m -Xmx1024m -Djava.awt.headless=true -Dorg.xml.sax.driver=org.apache.xerces.parsers.SAXParser -Dorg.apache.tomcat.util.http.Parameters.MAX_COUNT=1024 -XX:MaxNewSize=256 -XX:-UseConcMarkSweepGC -Dnet.sf.ehcache.skipUpdateCheck=true"
Also I have added the option tasomatic.maxmemory = 4096 to the file /etc/rhn/rhn.conf but the problem persist.
Any Ideas how to fix this?
