Creating/Updating an issue in redmine takes a long time.
After creating or updating an issue ruby interpreter try to connect lb-in-f109.1e100.net (173.194.71.109). Because of proxy server it cannot be done. But there are no changes in issue's status throughout proxy's timeout. If you created a firewall's rule blocking this connection immediately, issue will be created without any pause.
How i can configure ruby interpreter not to connect to network addresses?
