It's definenitely a file handle leak (well very much looks like it), this
was my first thought when this
happened to me. Almost exactly the same symptoms as Tony Dyson (see below).
Which GD are you referring to when you say . "I've rebuilt GD with the
latest version of the library > (1.4). Can you re-install GD and try
again?" as I have this
http://www.activestate.com/PPMPackages/zips/6xx-builds-only/GD.zip and it
still produces the same problem. I would also add that leaving out TTF from
the x & y labels and axis makes graph creation much faster. I now only use
TTF for the title. Each graph without x & y TTF takes about .75 a second to
create, with x & y TTF this is about 2-3 seconds for each graph.
Some GD::Graph settings from my program
$graph = GD::Graph::bars3d->new(639,265);
$graph->set_title_font('arial',24);
$graph->set_x_label_font('arial', 10);
$graph->set_y_label_font('arial', 10);
$graph->set_x_axis_font('arial', 8);
$graph->set_y_axis_font('arial', 8);
$graph->set(x_label => "$x_label");
$graph->set(y_label => "$y_label");
$graph->set(title => "$png_title");
$graph->set(cycle_clrs => 1);
$graph->set(bar_spacing => 3);
produces an error after my code creates 5 graphs

produces all my graphs. I have tried this with up to 100 graphs to be sure.
