abi_ added a project: Parsoid.

This seems specific to this page -- I tried a number of other pages and they all succeed. Do you know that this changed with this train?

This happened also in dewiki for every page and for discussiontools, now seems fine again.

I was able to reproduce the issue for a while with all the pages, but seems to be fixed now. Reducing the priority for this task.

We had an issue with x2 which I fixed a few minutes ago, so probably related

Marostegui claimed this task.

I think this is fixed, reopen if it is not.

This reminds me of T356157 – a very similar transient but reoccurring error.
