Comment 2 for bug 784837

I'm seeing this also. I've got the following packages installed on an Ubuntu 10.10 host:

ii glance 2011.3~d3~20110701.151-0ubuntu0ppa1~maverick1 OpenStack Image Registry and Delivery Service - Daemons
ii python-glance 2011.3~d3~20110701.151-0ubuntu0ppa1~maverick1 OpenStack Image Registry and Delivery Service - Python library

I suspect this may be a packaging issue, specifically around the glance-api and glance-registry upstart scripts in /etc/init. Perhaps you could do this:

exec su -c "glance-api >> /var/log/glance/api.log 2>&1" glance

... instead of:

exec su -c "glance-api" glance >> /var/log/glance/api.log 2>&1
