Git push deploy randomly failing on Heroku with TeamCIty

Question

We're seeing git pushes fail when pushing with our node apps from out CI server (TeamCity). It happens once in a while (about 1 out of every 10 builds) and I haven't been able to determine what is causing it. I've added a "retry if failed" step to the build and it always works on the 2nd try.

If I change TeamCity to do a fresh checkout on each build, it never errors out but more than doubls the build time.

FYI, the build process does a checkout, does a grunt build then commits the build locally so that the built code gets pushed to Heroku. I'm doing a force push which should cover that scenario:

git push -f git@heroku.com:myapp.git trunk:master

Here's the log excerpt coming back from Heroku:

通过使用Heroku Push推送来绕开Git管道，您可能会有更多的运气： https : //github.com/ddollar/heroku-push
