Though given the fact that simply patching the kernel (on the RAID fs) when there's no other disk activity slows to a crawl which I'm fairly sure it didn't used, certainly these app stalls are new. The only trouble is I don't have any iostat profile from say a year ago when everything was OK. So I can't be 100% sure the current thing of spikes of iowait and await etc didn't actually always happen and it's actually something else that's wrong. > Justin.
