Re: [Kimchi-devel] [PATCH v2] Increasing nginx proxy timeout

The 60 seconds nginx timeout is creating some issues with actions that takes some time to complete, like creating a VM with a NFS template. After 60 seconds without a backend answer, the user is presented with a 504 Gateway Timeout error. This patch increases the timeout to 600 seconds, 10 minutes. This is enough time to process all the backend requests and ensure that a 504 error will only occur in a legitimate error in the backend. The Timeout Monitor of cherrypy is also being disabled, since we're using the nginx timeout and the session timeout instead.
