Here's a more obvious snippet from the logs:

2018-05-09 16:36:21.577 7f12cf1c4700  0 log_channel(cluster) log [WRN] : 1 slow requests, 1 included below; oldest blocked for > 34.482641 secs

I'm not really happy whitelisting these types of warnings but we also need to quiet this warning. Any thoughts?
