Insufficient Java heap memory to continue operation

Dear Community,

I get the following error message again and again after running some saveas(gcf, 'test' , 'pdf'); or print figures.

Insufficient Java heap memory to continue operation

No close all, close gcf, clear all or any tool to clean the java heap http://www.mathworks.com/matlabcentral/fileexchange/36757-java-heap-cleaner helps. I send multiple error report from Matlab directly, but get no response. Last error message I got was:

Error using drawnow
Insufficient Java heap memory to continue operation

Error in prepare (line 44)
        drawnow

Error in print>LocalPrint (line 271)
        pj = prepare( pj, h );

Error in print (line 240)
    LocalPrint(pj);

Error in saveas (line 154)
        print( h, name, ['-d' dev{i}] )

Error in myClass/myMethod (line 45)
saveas(gcf, 'test', 'pdf');

If I restart Matlab it works for a couple of runs and then it crashes again. After each run I make a clear all and close all, but both commands does not help. In addition, I put the heap option to the maximum.

Thank you for your help in advance.

Best regards!

i get this from time to time as well when working with pictures or such. appart from : - running your code on a bigger computer, - restarting Matlab between each run, and - trying to make your code more "memory-friendly" (for example one a picture is saved and you don't need it any more, clean it in your code to save memory ressources) i can't help you much... it just sucks ! sorry

I got the same error and reached at here. In my case, if I made a figure invisible, the error was't generated.

    fig=figure('visible','off');
    plot(...);
    saveas(fig,'test','png');
    close;

I hope it's gonna work for you.
