[MLton-devel] GC question

[Alain Deutsch]

Stephen,

I was wondering about the GC operation under tight available
memory based on the crash.sml program I sent you earlier: if I
change in this test program the allocation requestion (i
Bigmem.test) from 512Mb to 1Gb then I get an "Out of memory
(forward) ....".

among the log messages, I get:

> [...]

> = 3M).
> [Requested 918M cannot be satisfied, backing off by 61M (need
> = 3M).
> fromSpace size = 1,284,046,848  toSpace size = 898,818,048
> [...]
> Out of memory (forward).
> Diagnostic: probably a RAM problem.

Is it in cases like this that we could benefit from copying to
disk ?

	Alain.
