Orca/perl does a poor job of releasing memory usage.  If you run orca in
daemon mode, I suggest you try restarting it automatically at regular
individuals to clear memory usage.  I have a cron that does this daily.  I
have not had any problems with graphs (about 300 systems) doing this, but
other may have.

Orca automatically scales the plot to your data to optimize your viewing
satisfaction I believe.  The units or 200m would equate to 0.2.  Rather
than cram a graph in 1/10 of the y-axis it changes the scale.  You can
force data and plot ranges in your orcallator.cfg file per plot with
variables like data_min, data_max, plot_min, plot_max.
