> Can you confirm this (because I don't have the 32-bit version installed)? It still stinks, especially because it "silently failed after hitting the threshold", but I personally would feel better about 10gen if this little story is true (i.e. they warn you about it not only in downloads page, but every time you run mongod).
Just as a data point, I installed MongoDB on 32-bit Ubuntu 12.04 from the Ubuntu repo. At no point during install or service startup does it say anything.
