Jenkins BUILD FAILED/CANCELLED on openshift

Question

I have problems pushing new code to my openshift application with jenkins. I have enabled jenkins from web console admin and it works(no custom settings). However I have to push at least 2 times before it pushes new changes to my app.
I have bronze plan. I use 3 apps (main app, database app, jenkins) and when pushing, jenkins creates 4th app.
Pushing new version of app takes a long time, since I upgrade search index after every push. When I push for the first time, this is what I get:

git push origin

Delta compression using up to 8 threads.

This is my second push:

Why my first push always fails? I do not see any error regarding jenkins in rhc tail myapp

Answer 1

When I push first commit, it yells BUILD FAILED/CANCELLED. On second push it is a success. If I do third push right after second, it is success too. Almost like jenkins app would hibernate, but it cannot. I have bronze plan and I tried to load jenkins url so I was sure jenkins app is running.
Only possible reason for first failed push that I can think of is that I have 3 out of 16 apps and probably 4th app creation takes too long and Jenkins does not wait and ends with error.

So I will just keep doing two pushes instead of one every time I want to push new version of my app.
