Description

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.
