Honestly, It seems to me like it's probably for bad mouthing Ruby without obviously have having used it yourself. Ruby's pretty popular here, I assume that your comment didn't sit well with the Ruby groups here. While my own feelings toward the language are ambiguous, if you flippantly insulted one of my babies (Haskell, Scheme) my knee-jerk reaction might be to downvote you. Hopefully I'd curb it. Despite the fact that you've given some concrete reasons for staying away from Ruby vis-a-vis a link, I think you might have run into a bit of a tl;dr there. You should enumerate your problems with the language in your comments, or risk being downvoted.
More to the point the topic wasn't really about obscure bugs in ruby. The backend was failing due to getting slammed which admittedly could make some nasty bugs surface.
What I think the main problem was is that you answered someone in an emergency with a probably unrelated blog link.
The original description was "server is crashing without leaving a trace", which sounds like an obscure bug to me -- certainly of the kind described in the article I linked to. It's as related as it can be given the info they gave when they originally posted their query.
