Run-Away memory use by fopen()

["Peter" <petere at connexus dot net dot au>]

Hi,

I've written a program that allocates a large number of small
buffers, then attempts to open a file to write them to disk
before continuing on.  Problem is, that when I try to open
the file, the fopen() does not return, and makes the process
sit there sucking up memory until there is not more memory to use.  If I move
the fopen() before I do any malloc()'s, or I make it such that less allocation
is happening, then the fopen()
works as expected.

Any ideas why this is the case?
