Manually triggering garbage collection

["Jean Krivine" <jean_krivine@hms.harvard.edu>]

Dear list,

I am running a memory intensive stochastic simulator written in ocaml.
After initialization of the data structure (which eats up a lot of
memory but that's normal) I observe a memory leak during the
simulation which should not be there.
I noticed that if I run Gc.major() every n computation events after
initialization (I can make n vary), then there is no more memory leak
(the memory the process is using is constant).

So my question is the following:
Is there a rational way to detect I should call for Gc.Major()? (for
the moment I am triggering it every n events which is arbitrary)

Thank you very much

Jean
