> Please see the attached patch for a proposed fix for a memory leak in =
authunix_create_default().
>=20
> The leak appears to have been introduced 6/19/2009 in Revision 194494 =
of lib/libc/rpc/auth_unix.c
>=20
> As you can see form the patch, the fix is very simple. The issue was =
discovered when tracking down some rather drastic increases in =
application memory footprint during certain types of workloads, and was =
eventually traced it to this (apparently) not very heavily used path in =
libc.

> I would appreciate hearing any comments/concerns with the proposed =
