Running out of memory

Hello,
I'm trying to solve the following problem. After building my geometry, creating my mesh and solving ist, I try to plot severalt streamlines with an automatic matlab function. This Matlab function gets the solved model as an input parameter and a vektor with the startingpoints of my streamlines. The next step is a for-loop loading a single set of coordinate (x,y,z), and run the following. My chain of thougt is, that after the streamline is exported to the text-file, it is deleted or replaced by the next coordinates, respectivly.
But after about 1000 streamlines the functions stops execution with the error message that java running out of memory.
Who can help me? I already tried to increase the max Java heap size to 1024...
Best regards Matthias
model.result('pg1').feature('str1').set('xcoord', X);
model.result('pg1').feature('str1').set('ycoord', Y);
model.result('pg1').feature('str1').set('zcoord', Z);
model.result('pg1').feature('str1').set('resolution', 'fine');
model.result('pg1').feature('str1').set('maxsteps', '500000');
model.result('pg1').feature('str1').set('back', 'off');
model.result('pg1').feature('str1').feature('col1').set('expr', 'es.normE');
model.result('pg1').feature('str1').feature('col1').set('descr', 'Elektrisches Feld, Betrag');
model.result('pg1').run;
model.result.export('plot2').set('filename', ['T:\Test\COMSOL_Multiphysics\Zwickel\3D\MATLAB_MODEL\Stromlinie_' Spannung 'kV_Element_' I '.txt']);
model.result.export('plot2').run;
