Both of my 2.4.23 boxes reports excessive size-64 objects

1) on my 512MB box, it's 3176370 3176442 64 53838 53838 1
2) on my 128MB box, it's 1223329 1223365 64 20735 20735 1

Is this really normal? Both boxes have been up for 2 days, but the 128MB
box is starting to show signs of getting slower and slower the more the
size-64 cache increases.

It looks unusual. Are you running any less popular device drivers or
networking configurations?

We had a couple of ext3/htree leaks which did this in 2.6. Nothing else
comes to mind.

Yup, it was an ext3/htree leak. I've been given a patch to test.
