Meteor: Unexpected mongo exit code 100. Restarting.Can't start mongo server
These are the steps that solved my instance of this problem.
- Delete
.meteor/local/db/mongod.lock - Delete
.meteor/local/db/journal/j.*(note: I only moved it just in case! ;D) sudo meteor
sudo might not be necessary but it was the only way back into the app for me. Hope that saves someone a bit of time getting back up and running.
