Nope i deleted the corrupted install, the only thing i have is the content of my output.log which i posted earlier.
There was this error :
TypeError: Parameter 'url' must be a string, not undefined
this error was repeating itself 3 or 4 times then the server crashed.
I had 900k documents in my objects database. After running the following, I now have 300k documents and mLab only shows 131MB:
db.objects.remove({_key: "ip:recent"})
db.objects.remove({_key: {$regex: /^analytics*/})
Thank you so much!
