The following error is being returned after a system restart (there was a lack of memory issue) before the restart.
The Phusion Passenger application server tried to start the web application by communicating with a helper process that we call a "preloader". However, this helper process sent a response that looks like gibberish.
The response is as follows:
The response is a blank. Although it is suggested to fill out a bug report, I do not suspect this to be a bug, as everything was working previously. the only diagnostics provided indicate:
PID 1554
x Receive and process preloader response — 0.4s
What can be done about this?
A server re-start fixes the issue. Satisfactory outcome, unsatisfactory motive...
