Raport generation causes out of memory

[cyprian]

Hello,

 

I'm using JasperServer v6.0.1 on Tomcat 7.0.59 JDK 1.7.

For report generation the REST v2 interface is used according to interface description  http://community.jaspersoft.com/documentation/jasperreports-server-web-services-guide/v56/running-report

My requirment is to generate about 100 PDF reports which contains one Custom Visualization Component  (http://community.jaspersoft.com/wiki/custom-visualization-component-v60x) generated by PhantomJS.

For report generation one JR session is used, when about 50 reports have been generated JVM reports exception
java.lang.OutOfMemoryError: Java heap spac

JVM memory configuration -Xms1024m -Xmx2500m -XX:PermSize=256m -XX:MaxPermSize=512M -Xss1024k

I don't know how to solve this problem.

Do you have any idea?

Is it possoble to clear the report cache?

 

Thank you.

If you can, try increasing your jvm memory. If that's not possible, try using JasperReport7s virtualizer.
