I've just reproduced this on 2.6.12-rc5.

It was hapening every 4 hours or so with 2.6.11.9. 2.6.12-rc5 ran for a week... The system is being used as a fairly high traffic NFS server.

If you need more information from my system, please CC my address with responses as I'm not subscribed to the list.
