#17 {main}Notes
Parsoid cache prewarm job started showing this problem shortly after deployment of 1.41.0-wmf.12 to group2 on Thursday last week (June 8th).
It's unclear where the problem originates exactly; neither the parsoid code nor the revision store code had code modifications in the relevant time frame, so I'm tagging the ticket with both components. Could be a data corruption problem, but then it's strange that the problem started happening right after the code deployment.
