Just searched around and found out that an app is turned "idle" after a period of inactivity. The thing is that my app on openshift goes idle even with activity.
Actually, it has been happening for a while but today I noticed that the app turned "idle" twice, and I was working and accessing it during the day, so automatic wake up feature seems non existent.
It's a scalable nodejs v0.10 app.
When I start ssh session I see this message clearly:
*** This gear has been temporarily unidled. To keep it active, access
*** your app @ http://xx-xxxxx.rhcloud.com/
We had been having a couple of problems with this specific issue but it should be resolved now. Can you please verify if you are still having this issue?
