De-railing and arguments aside, there is evidence that *something* can causing planes to stall out in one server more than another. Whether it's common or not, I don't know. Fairly rare, if I'm the only HTH host that regularly gets this problem (there was another host I don't remember, not a regular, that I encountered this problem with).
Do I think people go overboard a little with the theories? Sure! Do I think the symptoms are being glossed over by everyone else? Yes!. None of y'all is right. But don't block out something because you're biased about the source.
Keep it civil, keep it friendly, keep an open mind, and things get done.
Peace.
