504 Gateway Timeout happens once every few hundred requests

Hi,

I get a 504 Gateway Timeout error every few hundred requests while running my tests. Please see the response below. The requests have nothing special about them to get this error. I feel like this is on the NeoLoad side and not my server. Please suggest any ways that I can may be retry when this error happens, or atleast ignore this error so that my test doesn't fail upon this error.

This mostly likely is a network error between the servers involved. I doubt this has anything to do with Neoload itself.

The NGnix-based gateway between the Load Generator and your tested application raises time-outs.

504 means that the time-out is raised when the gateway waits too long from the tested server. It means your Server is overloaded.

What is typical in such situation: getting not too bad average response time but higher max time. If all requests are impacted, it's a general issue that may be related to the number of parralel connections accepted by the server (available Threads/Workers on Apache). If only a few requests are impact, then it's related to something more specific and business related (ex: long database query).
