git-daemon hangs in futex()

["Johan Sørensen" <johan@johansorensen.com>]

Hi,

I'm having an issue with my git-daemon (1.5.4.3 on ubuntu gutsy), it
works fine for a few minutes, then it hangs (eg, "git clone git://"
never comes past "initialized empty git repo" adnd just sits and
waits) and strace on the git-daemon says:
$ strace -Ff -p 27453
Process 27453 attached - interrupt to quit
futex(0x2b270fb50980, FUTEX_WAIT, 2, NULL) = -1 EINTR (Interrupted system call)

.. and nothing more. But, if I attach to the git-daemon process with
strace before that happens, git-daemon keeps on working fine, so I can
change the outcome by observing it which is always nice, but not too
helpful.
I don't think this is related to Wincents problem some time ago[1],
because I can reproduce this when running dashed/dashless and
with/without --detach regardless of my env. Here's my git-daemon args:
/usr/local/bin/git --exec-path=/usr/local/bin daemon
--base-path=/home/git/repositories --verbose --export-all
--pid-file=/home/git/run/git-daemon.pid --detach

I'm not even sure if this is directly related to git or if it's some
other library causing the futex wait, any hints would be greatly
appreciated.
