rmcv is right, never use <!! inside the calling context of a go. Go blocks are limited (by default) to 8 cpu cores. So it’s quite easy to deadlock if you do a blocking operation inside a go block. Use <! instead. Ofcourse you can’t use <! outside the lexical context of a go-block, so your code will take a bit of refactoring. My talk from Clojure/West might have a few ideas on how to do that ( https://www.youtube.com/watch?v=096pIlA3GDo )
