Stack Overflow Termination in fission experiment

Dear Fluka team,

I am new to fluka and while running a simulation i get the error message
"Stack overflow in Feeder. Execution terminated." I am unsure what this
means but i'm confident it is caused by my use of uranium 233 in a low-mat
card. In this arrangement it is expected for the uranium to undergo
fission (sub-critically) and i encounter the same problem when
substituting for other fissionable materials (uranium 235, plutonium etc.)
but not for regular materials such as uranium 238. Is this a limit of the
code or can chain reactions be calculated successfully? I have attached my
input file in case it is of use.

Thank you for your help.
Jack Benton
