Ember-cli: ERROR: f2d_register_rpc()

[chrishough]

I am running osx 10.9.3 and this error just started popping up when starting ember cli:

2014-07-03 20:01 ember48381 FSEventStreamStart: register_with_server: ERROR: f2d_register_rpc() => (null) (-21)

I was running node version v0.10.28 and after discovering this thread https://github.com/joyent/node/issues/5463 I upgraded to v0.10.29 but it did not fix the issue.

Is there a fix for this? Is this cli specific?

[stefanpenner]

never seen this specific error...

[stefanpenner]

do you have steps to reproduce?

Also which version of ember-cli?

[chrishough]

I just crank up ember server and I am running ember-cli: 0.0.36

=> I noticed we are running .37 now, let me try to upgrade and see if that fixes it.

[stefanpenner]

0.0.38 will hopefully drop tonight, so if you can replicate and provide steps to reproduce maybe we can squeeze in a fix for you

[chrishough]

coolio, I will let you know. I am hoping upgrading to37 will fix it. Processing that now. Do not let this hold up 38 :smile_cat:

I commented out the import for ember-data and ic-ajax b/c I noticed they were not in the upgrade. Odd. If you are pushing .38 tonight, I can hold off and give that a try.

[stefanpenner]

try intalling a fresh node used something like github.com/isaacs/nave

[stefanpenner]

seems to indicate to many FS watchers may be attached, or you have more then 1 watcher running on the same graph.

We plan to work better with sane, but introducing a project root and allow sane to handle nest directories better. I suspect 0.0.38 will help, as it again reduces the amount of nested dirs watched.

[chrishough]

odd, I closed down, restarted and the issue went away. I can close this for now, and I will let you know if it happens on .38. I rolled back to .36 for now.

[DougPuchalski]

This happens to me periodically as well, I think when breaking out of a running ember serve at the wrong time and things don't get cleaned up.

[Ghostavio]

started having this same issue on version 0.1.1

[jeffcressman]

Same here when updating from 0.0.44 to 0.1.1

Didn't happen during the first few hours of working with 0.1.1 but the next day it started to show up.

[hhff]

apparently updating to node 0.11 does the trick

[jeffcressman]

Updating to 0.11.13 is working for me so far.

v0.10.32 is the latest Mac installer from http://nodejs.org. I picked up from http://mazharahmed.me/upgrade-node-js-version-in-mac/ that you can use the npm package n to easily install multiple versions of node.

[jmonster]

googling around similar issues seem to come from watching too many files -- did a recent change in ember-cli increase the number of files that would get watched? any chance it's accumulating temp files, since people are seeing the issue creep up over time and go away with a reboot?

[jeffcressman]

The issue also usually goes away if I switch between node versions with n. Sometimes I have to switch a few times for it to work. Still faster than logging out and back in, which has worked for me instead of a full reboot.

I've been switching between 0.10.32 and 0.11.14.

[jeffcressman]

Actually, no, switching versions of node isn't doing the trick anymore either.

[WeHateNick]

Switching to 0.11.14 worked for me. Thank you @jeffcressman for the very helpful article.

[granteagon]

I'm having the same issue. I had this with grunt on a previous project. It was from watching too many files.

$: ember --version
version: 0.1.2
node: 0.10.33
npm: 2.1.3

[granteagon]

Over at grunt-contrib-watch they had a few suggestions. I tried both solutions unsuccessfully. The ember project I'm running is not a large one (only bootstrap and font-awesome installed with a few ember files). This seems like a significant problem.

[DougPuchalski]

Hoping that https://github.com/stefanpenner/ember-cli/pull/2458 fixed this, in ember-cli 0.1.3

[granteagon]

@aceofspades using n (suggested by @jeffcressman) and 0.11.14 fixed this for me, but I'm not confident it's a permanent solution. I hope #2458 fixes it too.

[consideRatio]

I'm running ember cli 0.1.4, node 0.11.14 (installed with nvm 0.12.1)

I've had this problem, with increasing frequency, my solution of restarting is becoming troublesome since i have to do it every 30 minutes or so now. I trigger the error when i restart the server.

So I'd say nothing has fixed this so far, ive got before and after upgrade of node, and before and after upgrade of ember-cli from 0.1.3.

@consideRatio if you are using sublime, make sure you are ignoring files sublime doesn't need to watch.

[consideRatio]

AND SOLVED! :dart: :D FUCKING AWESOME! THANKS A BUNCH GRANTEAGON!

(i added these folders to my exclusionlist in the myprojectname.sublime-project file)

{
    "folders":
    [
        {
            "folder_exclude_patterns": [
                "tmp",
                "node_modules",
                "bower_components"
            ]
        }
    ]
