Spike in Redis errors: "BUSY Redis is busy running a script. You can only call SCRIPT KILL or SHUTDOWN NOSAVE."
I think the Sidekiq limit fetcher is running a Lua script, which for some reason causes errors such as https://sentry.gitlap.com/gitlab/gitlabcom/issues/16351/.
I saw a flurry of these errors over the last hour: https://gitlab.slack.com/archives/sentry/p1481005620000087
Any ideas why this happened?
