Feature Request / Bug Report

What challenge are you facing?

There are situations where a developer will be monitoring their build from the build view in the UI, waiting for it to complete. We have run into a situation where the build page stops updating in such a way that it appears the build is stuck or blocking. More specifically: the build log stops updating, the build view remains yellow (in progress), and the "started" counter keeps ticking. The reality, however, is that the build actually finishes, but the web UI has simply quit updating. While I encourage folk to use Slack or other forms of notification, I could see how this could be confusing, and seems erroneous.

The following can also be handy:

• Concourse version: v3.9.0
• Deployment type (BOSH/Docker/binary): binary
• Infrastructure/IaaS:
• Browser (if applicable): 65.0.3325.181 (Official Build) (64-bit)
• Did this used to work? I believe this works in most cases

A Modest Proposal

I think this is a bug. I don't know what the solution is, but we hit this when we had a degraded Docker registry cause lots of timeouts and general slowness during the docker push phase. I'm not sure if these long io waits are the culprit here (5m+ with no events streaming to the UI, for example), but may be a clue.
