Hi,

an updated FC3/i386 box with mail server functionality accesses
O(1000) accounts over NFS (NFS server is a dated Tru64 Unixcluster).

The automount process consumes memory until we have to kill it, or the
machine starts oom-killing us. Here is a graph:

(We have also seen bad behaviour of rpc.idmapd in the past, and 200MB
looks a bit too much for mapping 1000 accounts)

As a side note: Even though there are only 1000 accounts on this
system, mounts are attempted on each forged incoming address,
e.g. there is a multitude of failing mount requests, perhaps that's
causing the large rpc.idmapd process space and automount's memory
consumption?

Anything else we can provide for debugging? Thanks.
