[Bug 1452312] [NEW] glance-registry process spins if rsyslog restarted with syslog logging enabled

[James Page]

Public bug reported:

When configured to log to syslog, if the rsyslog process is restarted,
then the glance-registry process goes into a spin, consuming 100% of CPU
- strace:

poll([{fd=3, events=POLLOUT|POLLERR|POLLHUP}, {fd=5, events=POLLIN|POLLPRI|POLLERR|POLLHUP}], 2, 60000) = 1 ([{fd=3, revents=POLLOUT}])
sendto(3, "<14>2015-05-06 14:58:16.186 2579"..., 112, 0, NULL, 0) = -1 ENOTCONN (Transport endpoint is not connected)
gettimeofday({1430924440, 430244}, NULL) = 0
poll([{fd=3, events=POLLOUT|POLLERR|POLLHUP}, {fd=5, events=POLLIN|POLLPRI|POLLERR|POLLHUP}], 2, 60000) = 1 ([{fd=3, revents=POLLOUT}])
sendto(3, "<14>2015-05-06 14:58:16.186 2579"..., 112, 0, NULL, 0) = -1 ENOTCONN (Transport endpoint is not connected)

This maybe related to bug 1081022 but that should have only impacted
12.04 deployments.
