Comment 21 for bug 1047566

I have 3 web servers running kernel 3.2.0-55-generic on ubuntu 12.04.3 and using nfsv4 which seem to ramp up in memory usage which I can't account for in /proc/meminfo. I also have 4 web servers running ubuntu 12.10 and kernel 3.5.0-18-generic with nfsv4 and those machines run fine.
