<div dir="ltr">Seems like a good idea. Had it been there it would have saved me a couple days of fruitless firedrills.<br><br>The problem isn't completely solved, I'm still seeing brief spikes of one minute load to as high as 7 or 8 (on a dual core machine) on kernel 3.2. It's not the constant, chronic load it was on the 3.0 kernel though, so that's something. For reference, under the same user load running a 2.6 series kernel, these boxes never registered a load average higher than 0.5.<br>
