It's also now the only thing that uses buffer heads in your config, so.. I assume it's not an option to try another filesystem on this setup, but it's entirely possible that the 2.6.x buffer-head removal has impacted XFS negatively - although I'm a bit surprised at how easily you seem to show problems, since XFS actually has active maintenance. Nathan - I don't know if you follow linux-kernel, but Jerome Pinot has been having bad slab problems for some time now. Do normal XFS users compile with slab debugging turned on? Linus
