For how long did this happen? Was it just a small bump?
I have checked s5 slaves around the time of this ticket creation and I have not found any significant delay, just small 1 second peaks (which might not be even real but only graphing issues), would that be enough to cause this error?
There is also nothing on the general shard lag around that time: https://grafana.wikimedia.org/dashboard/db/mysql-aggregated?panelId=6&fullscreen&orgId=1&from=now-24h&to=now&var-dc=eqiad%20prometheus%2Fops&var-group=core&var-shard=x1&var-role=All
