I dont understand why you are posting this on here? Is it to point at him and laugh? Its seems pretty childish to point out someone's hardship on here.
This is a JIRA. It became a story once you posted it and commented on it in Hacker News.
Just waiting for the inevitable "this would never happen with PostreSQL" comments to appear.
Many of us here just don't have time to waste on technology that purports to be suitable for high-end work, but then fails us time and time again. As this incident shows, MongoDB can, and often does, end up in this position of failure.
Anyone faced with a MongoDB failure of some sort shouldn't put up with it, and should be very vocal about it. It's important to let others know the problems that can be experienced when using MongoDB.
