Red Hat Bugzilla – Bug 433473
pulse cannot bind to port 539 after a restart, child processes still have it open
Last modified: 2009-04-16 16:24:03 EDT
+++ This bug was initially created as a clone of Bug #391131 +++
Description of problem: In the failover server (fos) configuration, the daemon
pulse leaves open a file descriptor for port 539 when it forks sub-processes.
This includes ALL user specified programs started in /etc/sysconfig/ha/lvs.cf
using the 'start_cmd' directive.
Unless ALL programs terminate (including user specified ones), the next time you
start pulse on the same host, it will fail because it can't bind to the port.
All child processes of the first pulse are bound to the port, making it
unavailable to the new pulse.
Version-Release number of selected component (if applicable):
How reproducible: 100%
Steps to Reproduce:
1. Configure /etc/sysconfig/ha/lvs.cf to have start_cmd call a program that
never ends (ie "while [ 1 ]; do sleep 10 ; done ; ")
2. /etc/init.d/pulse stop # fails over second node
3. /etc/init.d/pulse start
While fos, nanny, and pulse may need port 539 open, pulse should close the
descriptor before it calls "start_cmd".

Moving all RHCS ver 5 bugs to RHEL 5 so we can remove RHCS v5 which never existed.
