Problem with git push on (somewhat) large binaries

Hi,

I recently encountered a problem while pushing to a remote repository using
ssh
- this usually works fine (and did for the last ~500 or so commits with no
problem), and I was able to pin it down to one commit where somebody added a
bunch of somewhat large (but not *huge*) binaries - about 30 MBs of JPGs,
MOVs
and others overall in that commit.

What I see when I want to push out this branch is the expected:

Pushing to <xxx> Counting objects: 172, done. Delta compression using up to 2 threads. Compressing objects: 100% (72/72), done

..then gits starts to write objects, and gets to object 51 of 172. Then, all of a sudden, it gets progressively slower (Kib/s indicator drops from 600K/s to 200, then to 50, and further down) and then after a while it does nothing at all any more. Eventually, I get

Write failed: Connection reset by peer error: pack-objects died of signal 13MiB | 47 KiB/s error: pack-objects died with strange error error: failed to push some refs to '<xxx>'

Everything works when I rebase that branch so that I drop that one commit that adds the binaries, and then push out the result.

Upgrading the server from git 1.6.1 to 1.7.0.4 didn't help. I first expected a cygwin problem (yeah, some of us are on Windows unfortunately), but I tried it with a fresh clone on Kubuntu Edgy with git 1.6.3 - same problem. I also tried -delta on the binary files in question with .gitattributes as suggested somwhere, no luck.

SCPing my local repository to the server and then pushing "over the file system" there works, though.

Any ideas?

Thanks Tobi
