I can't reproduce this issue. Does this happen with every app, and with every URL endpoint? If not, what is the specific app/endpoint doing? When it hangs indefinitely, can you show me what passenger-status and passenger-status --show=requests say?

The issue occurs both with my app and with this minimal example (with 5.0.0.beta2 specified). It can occur at any endpoint and the request never hits the actual application. Encountered this on both my development machine and Heroku.
Here is the show-requests output.
