[Help-glpk] xmalloc: no memory available

I've got a model which needs a lot of RAM, event with a few datas, and
I've got a "xmalloc: no memory available". But it seems that it doesn't
use all my RAM is it limited to 512RAM or something ? (may be it's
freebsd which limits it ?)

Have you got any advice about it ?

I can see 3 possibilities (may be 4):
- glpsol using all my RAM (and my swap). --memlim nnn seems to allow
less RAM but not more RAM.
- glpsol doing some clustering. Is there any project about it ? any way
to do that ?
- change my model (of course) but it's not the purpose of what I should
-I've got 7 constraints, may be it would be possible to separate
them/stock them and merge them ? (I don't really know how glpsol works
but it seems to be possible)

Thanks for your help, and for this soft ;)
