[Pacemaker] corosync init script doesn't invoke cib?

[quanta]

Distro: CentOS
corosync-1.4.3-1
pacemaker-1.0.12-1.el5.centos

On one node when I starts the corosync, it doesn't invoke cib and attrd:

# ps -ef | grep [h]eartbeat
root      7821  7815  0 22:59 ?        00:00:00
/usr/lib64/heartbeat/stonithd
root      7823  7815  0 22:59 ?        00:00:00 /usr/lib64/heartbeat/lrmd
103       7825  7815  0 22:59 ?        00:00:00 /usr/lib64/heartbeat/pengine
103       8069  7815  0 23:03 ?        00:00:00 /usr/lib64/heartbeat/crmd

and I get the below errors when showing configuration:

# crm configure show
Signon to CIB failed: connection failed
Init failed, could not perform requested operations
ERROR: cannot parse xml: no element found: line 1, column 0
ERROR: No CIB!

`/var/log/cluster/corosync.log`:

crmd: [8329]: info: crm_timer_popped: Wait Timer (I_NULL) just popped!

service: connection failed
crmd: [8329]: WARN: do_cib_control: Couldn't complete CIB registration 5
times... pause and retry

(other node with the same versions is working fine)
