> Please see the attached patch for a proposed fix for a memory leak in authunix_create_default().
> 
> The leak appears to have been introduced 6/19/2009 in Revision 194494 of lib/libc/rpc/auth_unix.c
> 
> 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 fix.
