This error essentially means there is no free java memory to process your request, in this specific instance it relates to a report load.

There are 2 ways around this;

  • Option A: Increase java memory
  • Option B: Decrease amount of memory needed for the report to run.

For this post, I will simply increase the memory allocation for 'Option A',

Option B may need to be handled via the services team as there are many factors to take into consideration. If you wanted to go down that path, please reach out to us to get the ball rolling.


To increase the memory allocation, you will need to modify a particular file based on your start up method, different methods are listed here.

In my case I just modified the catalina.bat and increased the mem from 1024m to 4096m, and restarted Yf.
