I'm getting an error when I run lein ring server

Exception in thread "main" java.io.IOException: User limit of inotify watches reached, compiling:(/tmp/form-init8598167152512048606.clj:1:73)

This happens after the initial build succeeds. it takes a few seconds.

Seems to be fixed now....I wonder if it was because I had lein repl and lein figwheel instances running somewhere else.
