Meteor: unexpected mongo exit code 100

Question

I have just installed Meteor version 0.5.9 (45fef52095) to my CentOS release 6.3 (Final) server (Linux version 2.6.32-279.19.1.el6.i686 (mockbuild@c6b8.bsys.dev.centos.org)

Answer 1

I had this problem using Meteor 1.4 on Windows 10. However, I am developing the the same meteor application on an Ubuntu install. The problem for me was caused by differences in the way Mongo 3.2 is implemented on Windows and Ubuntu. My 64 bit Ubuntu install uses WiredTiger. However as it says in the Meteor documentation:

If you are using Windows or 32bit Linux, you can update your development
database to 3.2, however it will continue to use the MMAPv1 storage 
engine, as the 32bit MongoDB binary does not support WiredTiger.

Using meteor reset on Windows blew away the WiredTiger format database from Ubuntu, and then rebuilt it using the old MMAPV1 engine. This solved the exit code 100 error.
