rpc.mountd memory leak?

I am using 1.0.12 of nfs-utils (linux/x86). I have a problem in that after a while rpc.mountd starts to eat up gobs of memory (sometimes > 1GB) and usually I am required to stop/restart NFS services to regain memory. I do not have many exported filesystems and very few clients have anything mounted at a given time, so I'm not sure why it would need as much memory so I'm guessing it's some kind of leak. Please let me know what I can do to debug this situation.

thanks

Known problem (fixed if you use debian-unstable).

Apparently there is a memory leak in libblkid which mounted now uses.

There is also a smaller leak in mountd.

Maybe I should do a 1.0.13 which makes libblkid optional... NeilBrown
