[problem] out of memory

Hi All,

I have a cvs repository I try to convert to git.
I have used cvs2git (1 week old) to get the dumps from cvs.
To be able to do the fast-import import into the new git.
I had to use a bigger machine than mine (the big is 64bits, 8GB ram, mine is 32bits,4GB ram)
because on my machine git ran out of memory.
Once converted, I tried to do a clone, it ran out of memory on my machine.

 - version used for gitc
   - on my machine : 1.6.6.1
   - on the big machine : 1.5.6.5 (debian lenny)

 - Here's the list of the commands that failed out of memory (stop at 2.7GB memory consumed):
git for-each-ref
git rev-list --branches --tags

 - this command succeeded :
git rev-list --branches (80MB consumed)

 - some packing have been done :
git repack -a -d -f 
git pack-ref --all
(on the big machine, it fails on mine)

after the git commands keep failing out of memory, 'git rev-list --branches' included.

 - there is 2159 refs in the repository.

 - git count-objects -v gives :

count: 0
size: 0
in-pack: 133986
packs: 1
size-pack: 365678
prune-packable: 0
garbage: 0

 - I still have a copy of the cvs and git repositories for testing.

Thanks in advance for any help,
Frédéric Heulin.
