From 28e4b62bbe89641ef09313fc25e811108b2a48ee Mon Sep 17 00:00:00 2001 From: Rong-En Fan Date: Thu, 30 Oct 2008 01:54:31 +0000 Subject: [PATCH] - 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.
