Looking at the output of "sysctl -a" on a now almost idle machine I
see:
ITEM SIZE LIMIT USED FREE REQUESTS
~ [ .. ]
ata_composit: 192, 0, 12296, 124, 62341
ata_request: 200, 0, 24592, 108, 920945
~ .. shouldn't these be freed at some point if there's minimal disk
activity (and few dirty buffers, "systat -vm" says there are 7)? Or
am I
misreading this?
That does indeed look wrong. However I cant reproduce the problem
here on any of the machines I have 6.0 on, and I dont think a memory
leeak that severe would have survived this far, but I've been wrong
many times before...
I'll look into it as soon as I have a little more time than today..
