This is ubuntu 14.04

12:52 $ npm -v
1.3.8

12:56 $ node -v
v0.10.17

Does anyone know the cause?

I suspect you may be out of hard drive space

wyaeld · 2014-06-18T00:58:59Z

Nope, 50g free. I'll see if I can test later on the version prior to the
new watcher

Enospc is a posix error for error no space. I'm not sure how to interpret this in any other way

So I added a console.log to sane/index.js on l183 so I could see what dirs it blows up on.

I don't see what would be happening to cause the error though. There isn't anything unusual, and 40% of the volume is free.

matebn · 2014-06-18T08:14:16Z

I had the same problem.
Deleting the /tmp directory and rerunning "ember server" resolved it.

wyaeld · 2014-06-22T22:23:43Z

Ok, have actually found the solution. Its not actually space. Its a lack of file watches

http://stackoverflow.com/questions/16748737/grunt-watch-error-waiting-fatal-error-watch-enospc

The solution is this:

echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p

I suggest that adding a line to the README about this might be worthwhile.

There are some optimizations done in nodemon described here that might also be useful

stefanpenner · 2014-06-22T23:12:56Z

that makes sense

chrmod · 2014-07-01T09:28:32Z

@wyaeld thanks for solution, having this document somewhere would be great.
BTW, isn't it Sane problem ?

stefanpenner · 2014-08-04T03:29:26Z

@chrmod its actually just mis-alignment with sane and broccoli, i suspect both may need to be adjusted?

stefanpenner · 2014-08-04T03:29:58Z

closing because the workaround is good for now. Both san/broccoli are aware for future work to improve this situation.

betasve · 2015-05-04T14:38:47Z

Deleting the /tmp and changing the max watchfile number worked for me too. (thumbs up)

milosb793 · 2016-11-08T14:06:27Z

Changing watchfile worked for me too! Thanks!!
