java.lang.OutOfMemoryError: GC overhead limit exceeded

Hello everyone,

I've successfully managed to install the Pentaho Business Analytics Platform (CE) on my ubuntu instance in the AWS-Cloud.
I'm using MySQL as database for the biserver on the same instance and running my reports against another MySQL-DB running on another instance.
My server runs Oracle Java 8.

I've written a report in Pentaho Report Designer which works locally when I run it against a Test-Database with less data in it.
Now I've uploaded it to my biserver and try to run it from there (against my production Database with much more data in it).

Unfortunately I get this error after some time and the report never gets executed successfully:

I've already updated my start-pentaho-debug.sh with --XX:MaxPermSize=2048m.

The arguments in my start-pentaho-debug.sh file look like this:

Code:

CATALINA_OPTS="-Xms2048m -Xmx6144m  -XX:MaxPermSize=2048m -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8044 -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000 -Dfile.encoding=utf8 -DDI_HOME=\"$DI_HOME\" -Dh2.bindAddress=localhost -Djava.awt.headless=true"

I've also tried using the -XX:MaxMetaspaceSize flag, but without success.

Also, during (and after the crash) the website stucks and gets unusable for other users which are trying to navigate on it.

Anyone expecting the same problems?:confused:
Any hints what to do?:confused: Please help me.
