Kong db-less errors when /config command received

As soon as a kong receives POST /config?check-hash=1 start getting spew of errors in log that don’t go away. Can someone tell me if I am missing something in configuration for db-less that would cause this to happen?

This is a bug: https://github.com/Kong/lua-resty-worker-events/issues/19

The fix for it went in to Kong and will be available in the next version of Kong: https://github.com/Kong/lua-resty-worker-events/pull/20

Thanks - any eta on next release?

We are currently in an RC phase for Kong 1.3.

It usually takes a couple weeks for the final release to be generally available.
