Again, you're making the assumption that the problem may be due to these observable inconsistencies, denying the asker from getting an answer, and denying someone who knows a "normal" explanation that would have equally applied to the same software on a real server to publish it. I'm sure there are some fairly exotic server room configurations out there, which may also bring their share of uncertainties.

I'm not disagreeing with the fact that those slight customisations make the Pi belong elsewhere than SF, I'm disagreeing with the fact that you're assuming that whatever causes the problem in the question is due to one of these uncertainties, without giving a chance for the question to be answered.

What you're saying is that because there might be some uncertainty in the conditions where the system is running, a question cannot be given the chance to be answered, even if there is an actual more straightforward answer than one of the other SF users may know.

I'm not talking about anecdotes, I'm talking about the fact it's running Nginx on a Debian Wheezy (slightly customised perhaps). Are there no professional servers out there running Nginx on a Debian Wheezy?

It could have had an unpredictable behaviour, but it turns out that the question had a acceptable and accepted answer which seemed to provide a much more "predictable" explanation.

@WesleyDavid, most software is ultimately intended for production usage. It's quite useful to have the advice of sysadmins who're going to handle that software, as a developer in general. Again, pushing away those questions doesn't help. In fact, sysadmins are often the ones who have to deal with that software once it's written, so advice on the admin aspects should be on-topic.

Again, this meta question is about whether such questions are ever on topic, and whether to ban them purely on the mention of the RPi.

@NathanC, my point is exactly that this question is actually not specific to the Raspberry Pi (and thus doesn't really belong on that SE site), but it's rather Debian admin question related to Nginx and Django.

@ChrisS, sorry, I really didn't mean it in an offensive way. We all makes mistakes once in a while, I certainly do. I just found your edit at the time a bit odd, putting words that the OP had never said. I'm not not sure this sort of editing (coming from mods or anyone else who can edit) is a good idea, that's all.

@JohnGardeniers, sorry about that, I've just tried to shorten all this at the end. I was just hoping that more details and references could help see the problem.

No worries. It seems that the idea of editing that question isn't so popular after all anyway (I got a downvote today on the associated meta question). Why a mod would introduce a statement that could be considered as misleading in a question is not clear to me, more so because it also makes some previous answers look silly (see comments on the last one, for example). I'm not sure what to do about this...
