Still seeing the error for T268065 in production, but I can't replicate it locally.
Will check in again in the next deploy in January.

The e.off error looks eradicated but not the e.on error:

https://logstash.wikimedia.org/goto/298ed24dd7d5312b135c76eec4ade77e

The original bug report however is resolved, and given my inability to replicate the e.on error I think a new ticket should be opened for that.
