Makes me suspect there's actually a bunch of pagecache in the box as well, but maybe it's just coincidence, and the rest of the box really is full of anon mem. I thought we dumped the alt-sysrq-m type stuff on an OOM kill, but it seems not. maybe that's just not in mainline. >> This doesn't seem to happen every run, unfortnately, only >> intermittently, and we don't have much data before that, so >> hard to tell how long it's been going on. >> >> Still happening on latest kernels. >> http://test.kernel.org/abat/62445/debug/console.log > > The same appears to have happened there too.

Difficult to tell, it's a fairly new box to the grid, so it seems to have been doing that intermittently forever. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
