If I don't reboot every 15/20mins the machine suddenly starts thrashing like mad and then effectively locks up :-( Last night I tried reverting the dvb-core ringbuffer part of -mm1 and that didn't seem to help at all. I've just tried 2.6.16 with just the origin.patch from -mm1 and that has the same leak in it. So it looks like I should have spotted this earlier before it was pushed into 2.6.16+ Just double checked and in 2.5.16 sock_inode_cache isn't even on the slabtop screen. I suppose that leads to a new question - what's the easiest way to start to break down origin.patch and do you know of any likely culprits? I see Andi Kleen has seen dentry_cache leaking on x86_64 (this machine is x86(_32) uni processor.
