Comment (by mikeperry):
Ok based on the above, my suspicions are accumulating around some kind of
interaction between timed out circuits and the circuit failure limit,
which would explain why your services stop working. I do not know where
this CBT error is coming from though. #27049 is one way that it can
happen, but if there are no loglines related to that, then something else
must be happening.
I also do not know why this limit is only affecting v3 services. Perhaps
there is some v3-specific code that counts failures differently than v2.
Are you able to run branches with additional logging and/or potential
fixes? I have been unable to reproduce this on a v3-only service that is
under continual use via synthetic wget activity.
