Git push fails when modified files are included in push, but succeeds when added or deleted files

I've been using git for a few months and have never run into problems. I met my match today. I have a system running Ubuntu 10.10 (new system). I put my keys in place to access the server, and can ssh in just fine. I cloned my repos just fine. I can push added / deleted files just fine. However, when I try to push modified files, the push doesn't finish. It hangs on the last line (Starts with "Total")

If I wait 15 minutes or so it gives me these errors:

Write failed: Broken pipe Fatal: The r开发者_运维百科emote host hung up unexpectedly

I've tried pushing as both regular user and sudo user. When I add a verbose flag to the push, nothing.

I think this is an SSH error, but it is completely puzzling me. Can anyone help?

I'm just going to run a list of ideas here.

Is this plain SSH or are you using e.g. -o ProxyCommand or another tunnel of sorts?

• I'd check the version of the client, since you report being able to do the same correctly from other machines.

• I'd also try creating a bundle from the client to eliminate the transport from the analysis.

• I'd check file permissions (and out-of-space/quota/temp space for the user) on the server. Are you using the same user that works for other clients?

• You could look at a problem in the garbage collect step on the server (by using git config to make sure it doesn't happen).

• Did you try other protocols (git-daemon or smart http server?)

• Could something be up locally (like repository on synch NFS, or dropbox or...)?
