This is an indication that zuul (if you are using zuul) is unable to clearly communicate with Jenkins nodes. This is an internal error and has nothing to do with the patch. Please fix your system and post your incident report with details as a response. Please test your system on ci-sandbox after it is working again. Thank you, Anita.
