Re: [Axiom-developer] Memory limit.

[Fabio S.]

First of all, thanks for having isolated the question in a new thread.

Moreover, let me also say that my question arises from the fact that 
during some computations axiom aborts, after some hours, with the 
following error message

--------------
(150) ->

   >> System error:
   The storage for CONS is exhausted.
Currently, 65542 pages are allocated.
Use ALLOCATE to expand the space.

Before posting, I searched on the list archives.

Apart of finding a message of myself (in 2008) with the same
problem... :-(  I saw that the question is probably related to GCL but I 
couldn't realize how to solve it.
I tried

)lisp (ALLOCATE 'cons 200000 t))

changing the value in different ways but as long as I can guess from 
)lisp (room)
it doesn't increase the total amount of available RAM (i.e., maximum 
pages, which is always 262144, that is 1 Gb, if I am not wrong).

So, are you telling that I should install GCL 2.6.8 and after I would be 
able to increase it? How?
