Meteor hung when starting

When I try to start/build my meteor app, it will spike the CPU usage to 100% and memory to about 1.8G/0.8G but still hung in the "Building for web.browser " phase.

I googled a lot and tried trick like renaming large files to .es5.js and removing ecmascrpt package but no luck.

Any clue how to solve this? Need to make a build for tomorrow.


Couldn’t figure out why.
Trying out release 1.2.2 but so far no luck.

In case, it helps:

I was having too many files open which prevented Isobuild to finish.


Eventually I had to remove some large JS file that we could live without and then the build process succeeded.
