Updated to git-1.6.5.3-1 from Fedora rawhide and still git reflog ran
for >5 minutes at 100% cpu (I killed it, it didn't finish)

I'm pushing a copy of the whole repo (all 1.9G after bzip compression)
to

http://people.redhat.com/~eparis/git-tar/

Wowzers, that's big. Can you send just what's in .git?

So I zipped up just .git   1.2G.  I did a make clean and zipped up the
whole repo  1.3G.

Just started pushing the 1.3G file.

Maybe having a .git directory that large is the problem?

Shouldn't be, unless your repo is really badly packed.

What's the output of 'git count-objects -v' ?

count: 87065
size: 866744
in-pack: 1203497
packs: 148
size-pack: 976474
prune-packable: 1611
garbage: 0


It's not home movies   :)  .  It's a kernel trees with about 5
'upstream' trees that are remotes, which I update daily.  One of the
remotes constantly rebases every day starting with Linus' tree and
pulling in about 150+ branches of work from others all of which might
rebase.  I have (needlessly) the tags he keeps of that repo every day.
I daily rebase my work on top of that constantly rebasing tree
(linux-next) using stgit.

I noticed just blindly poking at sizes in my .git/object/pack that the
largest pack is a lot larger than the second and third largest....

And all total there is almost 1G of data in .git/object/pack

If the answer really is that I just have too much data and it can't be
handled, I'm fine exporting my patches getting some clean trees and
starting over till I get in this situation again, but if it really is a
problem/bug that can be solved, the full tar ball of my repo is at
