No response from OP in several weeks, closing as works for me. If more information is provided in the future this can be reopened.

It should indeed run octpy.exe because Python and SymPy are doing the actual symbolic computations. But later commands should reuse the same process.

1. Does the "Communication established" line show up each time you press F5?

2. Instead of "Run program (F5)", can you try typing some symbolic commands from the Octave command line? Does that still start more than octpy.exe?

(I don't really know what "Run program (F5)" actual does; maybe it starts a new clean workspace, in which case this might be the expected behaviour, although the processes shouldn't persist...)

3. What version are you using? This "bundle" package from github right?

every times that Run program (F5) , it creat one octpy.exe in
RAM memory , in win xp 32 bit .
code :
% this is just a formula to start with,
% have fun and change it if you want to.
f = @(x) x.^2 + 3*x - 1 + 5*x.*sin(x);
% these next lines take the Anonymous function into a symbolic formula
pkg load symbolic
syms x;
ff = f(x);
% now calculate the derivative of the function
ffd = diff(ff, x)

I'm not sure it be a bug.
