| 
| Bug report for Octave 2.0.9 configured for i586-pc-linux-gnu
| 
| Description:
| -----------
| 
|   Every second time I issue a plot command, for example
| 
| 	gplot rand(100,1) with linespoints
| 
|   I get the following error:
| 
| 	warning: connection to external plotter (pid = 858) lost --
| 	warning: please try your plot command(s) again
| 
|   When I try the command again it works. 
| 
| Repeat-By:
| ---------
| 
|  Every second plot command, they don't have to be the same, results in
|  the above written messages with no output of gnuplot.

You should only be seeing the warning message if the gnuplot process
exits unexpectedly.

Is something killing the external gnuplot process between plot
commands?
