[geeks] Problems with grep on leopard

[Sevan / Venture37]

I keep on getting the following error message when running grep on my
Application Support directory in my home directory

grep(236) malloc: *** mmap(size=1195270144) failed (error code=12)
*** error: can't allocate region
*** set a breakpoint in malloc_error_break to debug
grep: memory exhausted

The system is a 8 core Mac Pro with 9GB of ram. I've tried a fresh install on
another disk & still get the same thing, Apple Hardware Test says everything
is fine aswell.
Any ideas???
