> The log level of IOException was reduced to DEBUG for SLING-3498, to avoid polluting the logs with client disconnect exceptions, which are hard to identify reliably.
> The downside is that this hides legit IOException from application code, as debug logs are usually not enabled on production systems.
> We should find a better to way to separate client disconnects from application-level IOException, and log the latter in the usual way.
