Hi,
I got unexpected ERROR message when I tested Heartbeat process failure.
ha.cf:
-----
crm on
use_logd on
keepalive 1
deadtime 10
initdead 40
warntime 5
udpport 694
bcast eth0
node node01
node node02
watchdog /dev/watchdog
-----
heartbeat version: 2.1.4
OS version: RHEL 5.1
The test procedure:
1. start heartbeat
# /etc/init.d/heartbeat start
2. kill heartbeat process
# kill -9 <"heartbeat: write" or "heartbeat: read" process>
These processes are restarted.
3. stop heartbeat
# /etc/init.d/heartbeat stop
I get ERROR message in this stop process.
---- ha-log -----
heartbeat[4632]: 2008/09/09_14:43:41 ERROR: Watchdog write
magic character failure: closing /dev/watchdog!: Bad file descriptor
heartbeat[4632]: 2008/09/09_14:43:41 ERROR: Watchdog close(2)
failed.: Bad file descriptor
-----------------
I think that this is the same cause as Bugzilla No.1702 and I make patch.

Please check attached patch.
