Never-ending tab throbbers on Nightly with RCWN enabled on Bugzilla and Searchfox
There appears to be some kind of RCWN pref flipping experiment underway, and I'm in the cohort that's got it enabled. I've noticed that since that's happened, I'll visit Bugzilla or Searchfox pages, and the tab loading throbber will never quit, so the page looks like it's loading forever. Let me know if there's any diagnostic information I can supply - this is pretty easy to reproduce for me.
@junior can you provide suggestion to @mconley for further debugging on this issue?
ni? related people and block RCWN
The HTTP logs when reproducing the issue would be very helpful https://developer.mozilla.org/en-US/docs/Mozilla/Debugging/HTTP_logging#Using_aboutnetworking
I cannot reproduce it. Please, add also cache2:5 to MOZ_LOG.
@mconley can you help capture the corresponding MOZ_LOG by following comment #3 and comment #4?
I cannot reproduce it, either.
I've been unable to reproduce it reliably, though I still seem the bug. If it helps, this seems to occur after I've posted a comment to Bugzilla. I tried hammering on https://landfill.bugzilla.org/bugzilla-5.0-branch/ to see if I can reproduce it there, but no luck. Can I safely disable RCWN in about:config and not disrupt the experiment I'm in? That way, I can see if the problem seems to go away.

That way, I can see if the problem seems to go away. I think that should be OK. We only gather telemetry when the pref is on. Although getting the logs for this issue would prove much more useful in debugging it.

Understood - the problem is that I've had zero luck reproducing it reliably. Let's see if we can at least box it in with the RCWN flip, and work from there. Setting a needinfo? on myself to report back in a few days with observations on browser behaviour after flipping the pref.

The problem has not recurred since disabling RCWN. I'll now re-enable RCWN to see if it re-appears again.
I've had RCWN enabled for a while now, and haven't seen this recur. I'm going to close this as INCOMPLETE. Sorry for the noise, folks.

Thanks for reporting this. Hopefully it was fixed by something we deployed at some point.
