Comment 1 for bug 522296

I confirm that with 2a this doesn't happen: memory usage is then 900 MB. That's far less than 7GB, though 900MB is still quite a lot; I don't see well why so much memory is needed.
Anyway, I have the 1.14-repo check running now on a machine with 12GB RAM, for 24 hours already, and hope it will finish successfully.
