[Gnuplot-bugs] Possible bug related to data file size

[Charles A S. <Cha...@ra...>]

I apologize if this bug has already been reported - I searched the 
comp.graphics.apps.gnuplot group but didn't see anything.
I am not a regular reader of the group.

Using gnuplot version 3.7, I can plot data files containing in excess of 4 
million entries (haven't gotten to 5 million yet).
Using gnuplot 4.0, I cannot plot much more than 1 million data entries 
without something crashing.
In each case gnuplot is running on a UNIX machine to which I am logged in 
(from a Windows PC) using the Hummingbird Exceed tool.

Here is the output reported to me when it fails:
gnuplot> load "plot_03b.plt"
gnuplot> XIO:  fatal IO error 131 (Connection reset by peer) on X server 
"Lxxxxxxxx.dhcp.pts.us.ray.com:0.0"
      after 21702 requests (21692 known processed) with 2 events 
remaining.
(I replaced the actual machine name with Lxxxxxxxx)

Gnuplot version 4.0 is running on the following machine:
Manufacturer is           Sun (Sun Microsystems)
Manufacturer (Short) is   Sun
Manufacturer (Full) is    Sun Microsystems
System Model is           Fire 280R
Main Memory is            2.0 GB

Any idea what is going wrong?
Thanks.
