There is a huge memory leak in rpc.mountd with nfs-utils-1.0.12. The relevant bug is described in http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=413661 and it turned out it is really a leak in libblkid.so.1 of e2fsprogs package which is used now by nfs-utils-1.0.12. After a day, the rpc.mountd mem usage grows to serveral GBytes (on heavy nfs servers). nfs-utils-1.0.12 should be hard masked until the appropriate patch is applied to e2fsprogs.
umm, i dont think so ... you fix the source of the problem, not random packages that are affected by the actual problem
added the fix from upstream e2fsprogs repo to 1.39-r2: http://thunk.org/hg/e2fsprogs/?cs=5a2a75111d7a;style=raw
