IDL new graphics memory leak? [message #93713]

Hey,

I have some enourmous problem with the amound of memory (virtual) IDL is using. I believe they are resulting from my extensive use of plots and images using the plot/image functions from IDL. If I omit them from my code my memory usage is on a normal level (1-8gb). If I want to include plots and images then my usage of memory will grow till it overloads the cluster I am working on (200-400 gb). Right after saving them I destroyed the objects via obj_destroy. This didn't solved my problem so I used heap_free. Still no improvment. Is there anything I am missing here? I am using IDL 8.3 on linux 64 bit.
rough sketch of my program structure:

read file (big image)

For
For
data analysis
Img=image(...)
img.save,....
destroy img
plot=plot()...
...
endfor
endfor
end

Thanks in advance!
B.R.
