Details:

% Iterating "saveas" or "print" function crashes after many iterations (e.g.
500):

% given the following set up where we have an array of vectors we wish to
plot, loading vectors in loop, performing plotting, labelling and saving works
successfully up to a limit. Above this limit, the octave engine crashes. In
the GUI I reach a limit of 505 plots, in the CLI I reach the limit of 509
plots.

for i = dataIndex = 1:N %(e.g. N = 1000) 

    v1 = csvread(strcat(PATHTOFILE,v1Data(dataIndex ).name));
    v2 = csvread(strcat(PATHTOFILE,v2Data(dataIndex ).name));

    % assuming length(v1) == length(v2) - my measurements were length(v1) ==
length(v2) == circa 40 to 50

    h = figure;

    plot(v1,v2,'-ob');

    title(num2str(dataIndex));
    u = max(max(v1,v2));
    
    xlim([0 u]);
    ylim([0 u]);
    xlabel('v1');
    ylabel('v2');
  
    drawnow;

% following assumes filenames are preallocated in filenameout:
     saveas(h,strcat(SAVEDIR,filenameout(dataIndex).name,'.png'),'png');
    % OR:
    %print(h,strcat(SAVEDIR,filenameout(dataIndex).name,'.png'),'-dpng');
    

    close(h)

end


The Windows system resources are very far from saturation. Can anyone else
replicate this condition or similar?
