6 instances on Oct 11. Hard to debug without a URL to go with it though. So, let us keep this phab task in the backlog for now.

From the req id back to Logstash... Does the page id, rev id etc help?

Yes, that helps. I was looking in the structured fields, and never paid attention to the message. :) https://zh.wikipedia.org/wiki/%E7%A8%8B%E7%A7%80%E6%B0%91?useparsoid=1 crashes and I can debug that.

ssastry added a comment.Oct 13 2025, 2:04 PM

This snippet: <ref>foo {{start box}}</ref> is enough to reproduce this on zhwiki. Clearly markup error because why would you start a table and leave it hanging inside a ref tag? But, we shouldn't crash on that snippet. Will fix tomorrow.
