This is super rare (happened **once**) and literally the only log message written to Logstash, with any channel or severity, for load.php requests in 12 hours, but here goes:
```
type=mediawiki channel=DBReplication level=WARNING
url=/w/load.php?...
trace=

```
It's probably harmless but would like to make sure to understand if this has any impact, and whether it could potentially be avoided, and if not, whether RL should do something in return.
