java.lang.OutOfMemoryError: PermGen space in struts2 to birt integration

braju

Hi,

We have Struts2 integrated with Birt 3.2.21 in our application. After execution of couple of reports i am facing OutOfMemoryError PermGen space issue. On the contrary if the application is accessed without using the reports the application works fine for hours.

java.lang.OutOfMemoryError: PermGen space

java.lang.OutOfMemoryError: PermGen space

Please help me if anyone has already encountered it or have any knowledge of how to resolve it.

Try upping your permgen space to see if that fixes the issue. Is there any way you can upgrade to a newer version?

Which version of BIRT is that? 2.6.0? I'm pretty sure there was a memory leak issue in a couple versions around the 2.6 timeframe that were fixed with BIRT 3.7. Is there any way you can upgrade to 3.7.2+?
