Facilitating: Grace Gellerman


  • We'll be meeting soon to go over the RESTBase / Node.js service content spike


  • We spent part of last week figuring out load issues on the Parsoid cluster
    • The deploy of on Jan 28th exposed a few latent bugs in Parsoid on a tiny subset of pages. in particular caused those pages to send Parsoid into an infinite loop, and our timeout handling wasn't properly killing these stuck processes in all cases. This caused load spikes Thursday and Friday because of repeated retries on 2 enwiki and 3 plwiki pages. The repeated retry from the job queue is The infinite loop bug has since been fixed and the fix deployed and load is back to normal since Saturday.
