git update-ref --stdin : too many open files

Hi,

Steps to reproduce:

$ git --version git version 1.9.1 $ wc -l /tmp/1 9090 /tmp/1 $ head /tmp/1 delete refs/pull/1/head create refs/heads/pull/1 86b715f346e52920ca7c9dfe65424eb9946ebd61 delete refs/pull/1/merge create refs/merges/1 c0633abdc5311354c9729374e0ba25c97a89f69e ... $ ulimit -n 1024 $ git update-ref --stdin < /tmp/1 fatal: Unable to create '/home/gitmirror/repositories/Ceph/ceph/refs/heads/pull/1917.lock': Too many open files $ head -20 /tmp/1 | git update-ref --stdin $ echo $? 0

The workaround is to increase ulimit -n

git update-ref --stdin should probably close some files.

Cheers
