Author: rafan Date: Thu Oct 30 01:54:31 2008 New Revision: 184459 URL: http://svn.freebsd.org/changeset/base/184459 Log: - Whenever a password/shell is changed via rpc.yppasswdd, the daemon leaves one zombie process because it does not do the cleanup. For a long running NIS/YP server, it will have lots of zombie processes on it. Fix that by ignoring the SIGCHLD signal since we don't really care about the exit status in this case.
