I had a perfectly functioning Meteor app. Today, I've updated it from Meteor 0.7.1.1 to 0.7.1.2. Upon starting the app, I get
Unexpected mongo exit code 100. Restarting.
Can't start Mongo server.
MongoDB had an unspecified uncaught exception.
Downgrading to 0.7.1.1 didn't help, nor running mrt reset, removing mongod.lock file and killing mongo process, as suggested here, here and here. Is there something that 0.7.1.2 could have broken? What more can I do to fix the issue?
