Impact

There are some dozens of these occuring in production. Not huge numbers, but enough to make me worried, as train conductor. Would appreciate it if someone who understands the code took a look.

Will look at this sometime today if someone doesn't beat me to it. Daniel is out this week. Adding @Pchelolo and @DannyS712 (who have also recently worked on Revision code) and @CCicalese_WMF (who is currently on Platform Team Clinic Duty).

If I'm reading this correctly, the error is occurring in 1.36.0-wmf.1, but 9bd04f784566 didn't hit until 1.36.0-wmf.2. Let me know if I'm not looking at that correctly.

Not that this doesn't need investigated, and I'll continue to look. I'm just thinking 9bd04f784566 is not the cause.

I'm no train log triage expert, so I could be misinterpreting. But looking back over the last couple of months, I'm seeing this in multiple mediawiki versions, and I'm not seeing an enormous spike in recent frequency. Maybe the last few days have been slightly higher, but not by orders of magnitude. So from a train conductor's perspective, I'm not seeing anything worthy of train blocking.

I'm tempted to triage this on Platform Team Clinic Duty as Medium priority. In practice, that means it may float around on the workboard for some time. Let me know if you think this is more urgent.

Debugging note: for whatever reason, the majority seem to be coming from ruwiki. Unsure if this is significant.

From a train blocker point of view it's not urgent, but, speaking as someone on the train conductor rotation, every error message in logstash adds to the friction of the train, and increases the burden of making sure nothing's broken. From that point of view, fixing non-blocker error messages would help make us run the train faster, and more often.

@BPirkle thank you for your analysis, much appreciated.
