[Buildbot-devel] git fetch hangs on large repos

I am having a strange problem with git and I hope to get some insight
from this list on what the cause might be.
This build step:
hangs for large repos, such as GIMP. Smaller repos, such as
"git://git.gnome.org/babl", works fine.
I've been doing a fair amount of debugging, but I don't get much wiser:
* When the git-fetch hangs, git-fetch waits for git packs
from the git server, but no data is coming. It blocks in
read() on the server data socket.
* I run my buildbot as myself (user 'martin'). Still, when
I replicate the commands manually in a bash shell that
buildbot executes, things work fine. I don't find anything
strange in the environment variable dump buildbot does.
* Running a git-daemon myself, exposing a bare GIMP repository,
buildbot manages to fetch using the git:// protocal from that
* I've been doing a tcpdump of the traffic between git-fetch
and the server, and git-fetch successfully gets a list of
remote refs from the server. I can then see that git-fetch
sends a list of commits that it wants from the server, but again
doesn't get the data it asks for.
Thanks in advance for any insights you might give.
