Describe the bug
After enabling garbage collection in one of our Werft installations, the WebUI became unresponsive after 30~40 minutes.

We noticed errors when the Web UI performed the ListJobs method.

Meanwhile, we also noticed the lack of logs being emitted

To Reproduce
Start a Werft instance with the configuration from this PR.

Expected behavior

  • Web UI to continue being responsive
  • Logs regarding garbage collection being emmited

let's schedule https://github.com/gitpod-io/ops/issues/1358 again when this issue is fixed.

I can't really reproduce the issue. I took a DB dump from werft.gitpod-dev.com and tried to replicate the problem. Everything works as expected.

It might be the logs (see linked PR), or some lock in the DB.
Next time we try and enable GC, I'd like to look at the DB and see if there's a problem.
