Sorry, But I have already made this without any success. I really think that the issue is the size of this file. But we never know so I redo it again and here you have the result:
$ free
total used free shared buffers cached
Mem: 3954752 662264 3292488 0 17304 233092
-/+ buffers/cache: 411868 3542884
Swap: 8385920 0 8385920
[epuerto@epuerto-FC10 My_Ubuntu_8.04.2]$ for i in All-f00?.vmdk; do git add $i; done
fatal: Out of memory, malloc failed

I do nothing else, only a top to know the memory use and I see that just before this 'malloc failed', I have something like this:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
4323 epuerto 20 0 2115m 2.0g 2.0g D 20.2 51.7 0:24.64 git
And you can see that it appear some memory allocation is not free after this 'malloc failed' error.
If you have any suggestion, any test (or beta version with more debug message) I can do, you are welcome.
Best regards,
Emmanuel.
