Dear list members,

I am trying to run a stochastic simulator (written in ocaml) on a huge
data set and I have the following error message:

sim(9595) malloc: *** mmap(size=1048576) failed (error code=12)
*** error: can't allocate region
*** set a breakpoint in malloc_error_break to debug
Fatal error: out of memory.

My system:

Mac Pro running OS X 10.5.4
Processor:  2 x 2.8 GHz Quad-Core Intel Xeon
Memory:  10 GB 800 MHz DDR2 FB-DIMM

Does someone know what happened? Do you have any idea of any parameter
I could tune in order to avoid that?

Thank you very much!

Jean
