#2629 — gnuplot freezing on Windows 7 when using pipe

Hi all,

I have been using gnuplot to display data as it is acquired during an experiment.  I do this with a pipe from my data acquisition program to pgnuplot (on Windows 7 professional).  I am using gnuplot 4.6.0 with a slightly modified pgnuplot.exe - the only thing I changed was increasing the timeout period from 1s to 3s (1s was not enough time on my system - don't know why).

I notice that sometimes gnuplot freezes during the experiment and I have to do a hard reboot of the system - task manager is unable to stop gnuplot - the system is frozen solid.

Today, I tried rebooting the computer normally between experiments to see if this would prevent the problem, but on the second experiment (after the reboot), I still ran into this problem.

I have used this approach of piping to gnuplot from the data acquisition program with two other setups in our laboratory - one was same experiment (so same acquisition program), but on computer with Windows XP, and the other, a different experiment with a computer running Windows 7 (I think professional version, as well) - but have not encountered this problem with these systems.

Any ideas what may be going on, or how I can figure out what is causing this?

Thanks in advance for any help,

Jason McLafferty
