Hello,
It would be useful if you could post your code, or provide
a link to it (as a .txt file).
I have not come across this myself although it seems like it
would happen if you are doing something pathological (meant
in a good way :). If you can figure out where this problem
is happening (chop you script up into bits, put print
statements into it, comment out code etc.) this will help
us help you more quickly. Or maybe you will see the
answer right away. Especially if you are doing anything
you aren't sure about, or that might be putting heavy demands
on the system (recursion, tons of arguments, whatever).
