Description of problem:

rpc.mountd leaks memory when using a netgroup in /etc/exports.
On one system it leaked about 1MB every 7 minutes which caused
the system to kill the process about once every 2 weeks or so
when it gets past 2GB of memory usage.

No memory leak is detected if the netgroup is replaced by a listing
of hosts or ip ranges, rpc.mountd stays around 2.5 MB memory usage.

I think the problem is a documented one in the innetgr function in glibc 
and fixed in a rawhide/FC5 release :

http://sources.redhat.com/ml/libc-hacker/2005-09/msg00031.html

But it would be REALLY nice to roll a FC4 update for glibc with this
small patch in.  It would appear to affect all applications that access
netgroup for host permissions


Version-Release number of selected component (if applicable):
glibc-2.3.5-10.3

How reproducible:
Always

Steps to Reproduce:
1.Create a valid /etc/netgroup file
2.Add the netgroup to an NFS export in /etc/exports
3.Start NFS server and try lots of mounts, unmounts, failed mounts, etc
  
Actual results:
rpc.mountd memory usage grows unnecessarily

Expected results:
rpc.mountd should not grow more than to a few megabytes or memory usage
