I’m guessing it might be hard to reproduce - from looking at Zach’s code, you only get that WARN message on 1 in every 1024 deferreds
(https://github.com/ztellman/manifold/blob/master/src/manifold/deferred.clj#L565)
hmm, that’s literally all the logging I get (the quoted section above) - I’ve not noticed any other adverse behaviour. I suppose a custom deferred + more verbose logging of all my endpoints might reveal something - but it doesn’t look like a high priority from where I’m sitting right now.
@peterwestmacott I'm pretty sure that Yada returns another error status code instead of the 406
so you won't see any problems in your service
