Table grouping BIRT.- java heap space [message #879775]

First, sorry for my English.

I have a server with the following features.
- 64-bit Architecture
- Operating System Centos 6
- 20 Gb RAM
- Apache tomcat 6
-> CATALINA_OPTS = "-Xms4000M-Xmx8000M-XX: MaxPermSize = 512M"
- WebViewerExample 3.7.1

I run a report with 40 columns and 1000 rows.
This report has grouping, computed columns and summations.

After some runs the system returns "java heap space" and "java.lang.OutOfMemoryError: GC overhead limit exceeded"

What I can do?

Can you open a bugzilla entry for this?

I located two similar bugs:

- Bug 282492
- Bug 371814

I'm trying to set up the project in eclipse to debug it, but always I have over 1000 errors. Is there a guide recently?

Thank you!!!

What is your jdk release? It is probably due to a too long Garbage Collector, not really a memory issue. You should try to reduce the JVM young generations heap, something like -Xmn1500M

The -Xmn option controls the JVM young generation heap size. If you use a Java console or a JVM profiler, it relates to the 'Eden space' memory and the first 'Survivor space' level. I suspect it may be too large in your context, for reports wich create tons of small temporary java objects. And then the Garbage collector duration could exceed the default time allowed.

This is just a suggestion, please let me know if it helps.

(-Xmn) This was not a solution.

This report contains:
- 70 columns
- 1 group by 1 column
- Summations by group
- Total Sum

I can do?

Error identification:

The attached file shows the command "top".

I have identified that the reserved memory performance increases every report. BIRT is not releasing memory.

I doubt it matters but I set mine in JAVA_OPTS and I use
-XX:MaxPermSize=256m . Again I do not think it matters but I have no
space after -XX:

Can you add your issue to a comment on this bug:
