Sorry for replying to my own email:
At least in my case I found out what is eating the buffers: nfsd does!
The buffers stop increasing as soon as I stop nfsd. However, they start
increasing as soon as I start nfsd again.
Are there any ideas how to fix this? Downgrading back to 7-stable is not
really an easy task as far as I know, and I need the server to run without
having to reboot it once for twice a day...
