[Bug 1422317] Re: Juno glance spins with use_syslog=True
The switch to oslo_log from glance/openstack/common/log.py is not going
to be backported to stable/juno, no. This is definitely something I have
heard of people encountering before (and I'm frankly surprised there
wasn't already a bug for it).

Title:
Juno glance spins with use_syslog=True
Status in OpenStack Image Registry and Delivery Service (Glance):
Invalid
Status in Glance juno series:
Triaged
Bug description:
With syslog enabled on Juno (use_syslog=True in glance-api.conf),
glance spins on startup, consuming all available CPU cycles.
With some carefully placed calls to exit(), the line in glance causing
the problem was determined to be
https://github.com/openstack/glance/blob/stable/juno/glance/openstack/common/log.py#L523.
After this point the code gets lost in
logging.handlers.SyslogHandler().
I noticed that the <component>.openstack.common.log source file was
somewhat different in glance compared to several other OpenStack
components. An update to glance.openstack.common missed the juno
branch by a couple of commits
https://github.com/openstack/glance/commit/d4f890798a0588a80e21fad044d4df5d0964dc70.
Cherry picking this commit fixed the issue for me.
