out of memory rendering 38000 records [message #233489]

Hi !

I am using birt2.2M5 and launching jboss with these parameters:

JAVA_OPTS="-Xms256m -Xmx512m -XX:PermSize=64m -XX:MaxPermSize=256m
-XX:+AggressiveHeap -Dsun.rmi.dgc.client.gcInterval=3600000
-Dsun.rmi.dgc.server.gcInterval=3600000"

Using the birt viewer application I'd like display a report with about
38000 records. My laptop has 1GB of Ram.

I run into java.langClassCastException: java.lang.OutOfMemoryError with
no Stack Trace

The problem seems to be present during the rendering phase, when I see
that my disk starts swapping and working very intensively for some
minutes before getting into the above exception.

I use the query (the one of 38000) inside a summary report (with two
other very intensive queries),and it works greatly displaying the
aggregate results (it's a total sum of money).
The problem occurs when I want to show the details of my report and
render my 38000 records.

Any suggestion to solve this problem?

Thx,
Nico
