In https://wikitech.wikimedia.org/wiki/Incident_documentation/20150103-Parsoid requests to a specific page seemed to be retried a large number of times. Since requests for this page locked up parsoid workers, this led to the parsoid cluster being quickly overloaded. We should check why such a large number of retries are happening. Things to look into: - Varnish backend retries on timeout (both frontend and backend) - Parsoid job retries
