Public bug reported:
After a week or two of running, I found rpc.mountd eating large amounts
of memory:
top - 16:18:47 up 76 days, 8:59, 3 users, load average: 0.62, 0.43, 0.35

This is a fairly busy file server, with several hundred clients. I use
netgroups for access control. I see the debian nfs packages have had
some memory leak bugs fixed relating to netgroup and rpc.mountd, so I'm
probably seeing at least part of that same issue.
