When reloading config (specifically for proxy_pass) - occasionally this will be seen: nginx: [emerg] host not found in upstream
However - the upstream server's name WILL resolve in the os (linux) - only nginx seems to have this problem.
This seems to be a recent regression - as it didn't seem to happen previous to 1.0.10 versions.
Has anyone noticed this recently?
Trying to narrow down places to search.
