Bug Description
rpc.gssd appears to be leaking a small amount of memory every time it's used to authenticate a kerberized nFS mount. I can reproduce by running:
while sleep 1; do mount -o sec=krb5 nfsserver:
While running this in a loop, you can observe from rpc.gssd's /proc/<pid>/status file that its VmRSS grows indefinitely, generally by about 4 kB per mount request. On some of our servers that have a high turn-over rate of kerberized NFS mounts, we've seen the rpc.gssd process grow to more than 600 MB!
This happens on lucid with nfs-common 1:1.2.0-4ubuntu4.2.
I haven't been able to reproduce on precise with nfs-common 1:1.2.5-3ubuntu3, but this is still an important bug for lucid.

Hi,
I am still looking into the root cause of the problem. Thank you for your patience.
