Running "watch" task Waiting... Warning: EMFILE, too many open files '../..'

Question

So i'm having issues with my grunt watch it doesn't seem to be picking up the changes whenever i make a change but a minute later my console seems to be spammed with the following error

Running "watch" task
Waiting...
Warning: EMFILE, too many open files '../..'

It's them spammed with the following lines.

(node) warning: Recursive process.nextTick detected. This will break in the next version of node. Please use setImmediate for recursive deferral.

Followed by

util.js:35
  var str = String(f).replace(formatRegExp, function(x) {
                      ^
RangeError: Maximum call stack size exceeded

I've changed the ulimit but this has had no effect and is still producing the same errors... This is the configuration of my grunt file.

Answer 1

Check whether the folder you have grunt stuffs is in symlinked with other ,it may cause this ,Remove the link and try once Try grunt watch --verbose as well. Make sure it's matching all the files you're intending (maybe a file pattern running wild?)

Answer 2

Try below and increase the temp space ulimit -n 10480

If above is not working try hard restarting the system.
