Hi, We have a long-living issue with deadlocks in nailgun which used to almost harmless and caused rare test failures. But test failures become more frequent and today there is ~20% probability that they will fail on a working code, which is really annoying. Moreover, a few weeks ago it started to affect UI functional tests: cluster reset task may hang <https://bugs.launchpad.net/fuel/+bug/1529613>, so this issue now may affect real deployments. I think we need to do something with it ASAP. -- Vitaly Kramskikh, Fuel UI Tech Lead, Mirantis, Inc. -------------- next part -------------- An HTML attachment was scrubbed...
