Description of problem: If (cman) corosync is killed, pacemakerd notices and attempts to shut down pacemaker gracefully. However any clients using the cman API try to call cman_stop_notification() which writes into the now dead pipe and are killed with SIGPIPE. Version-Release number of selected component (if applicable): Version : 3.0.12.1 Vendor: Red Hat, Inc. Release : 32.el6_3.2 Build Date: Tue 20 Nov 2012 06:12:23 EST How reproducible: 100% Steps to Reproduce: 1. Start cman 2. Start pacemaker 3. killall -9 corosync Actual results: Client (crmd) using the cman API terminates with SIGPIPE Expected results: Connection is gracefully closed out.
