I have a Python 3.3, mongodb, cron webapp on Openshifts free tier.
I know that the Openshift free tier has a 5 minute time limit for running cron jobs or external processes. As an experiment I tried running my task in a thread off my main web app.
I would think since the task a thread it would not be subject to the 5 minute limit because it's all apart of the main web app process.
However, when I start my app which starts the thread task the app gets shut down in 2-3 minutes and give a 502 proxy error. A restart is necessary. I pulled this from the 'tail'
Any ideas what is going on? Does Openshift a CPU cycle limit also? Am I hitting some resource limit on Openshift? Any way to tell?
