Comment 2 for bug 1363102

This is caused by the some issue with syslog domain socket

> ps aux | grep glance-api
....
glance 49165 42.0 0.2 139304 44020 ? R Aug27 1000:18 /usr/bin/python /usr/bin/glance-api
....

> strace -p 49165
....
poll([{fd=3, events=POLLOUT|POLLERR|POLLHUP}, {fd=7, events=POLLIN|POLLPRI|POLLERR|POLLHUP}], 2, 60000) = 1 ([{fd=3, revents=POLLOUT}])
sendto(3, "<151>glance-api 2014-08-28 03:01"..., 258, 0, NULL, 0) = -1 ENOTCONN (Transport endpoint is not connected)
....

fd=3 is closed, but glance-api is constantly try to send data over it.

> ls -l /proc/49165/fd/3
lrwx------ 1 glance glance 64 Aug 28 08:39 /proc/49165/fd/3 -> socket:[380252]

this is some kind of socket

> netstat -nap | grep 49165
EMPTY

My bet, that this is unixsocket
