[Help-gsl] memory allocation problems

Dear All,

I have written a function for an MCMC algorithm.

I mainly use: --gsl_vector_alloc-- and --gsl_matrix_alloc-- and I have
quite a few, such allocations within a "for" loop. At the end of each
iteration I use --gsl_vector_free-- and --gsl_matrix_free--. (number of
iterations = 10.000 at least)

The program runs for small sizes (50x5, for instance) of these matrices
but when these sizes are slightly increased (70x5, for instance) I get
the following message:

gsl: init_source.c:46: ERROR: failed to allocate space for block data
Default GSL error handler invoked.

I am running the program in Unix, and in my account I have quota (1 GB).
I noticed that a (large=600MB) "" file is then created and my
quota is exceeded. Is there any relation?

How could I solve this problem?

Thanks in advance for your help.
