heartbeat not able to start local resources

Hi,

I recently upgraded heartbeat to version 2.0.2 with packages installed:
heartbeat-stonith-2.0.2-1
heartbeat-pils-2.0.2-1
heartbeat-2.0.2-1
heartbeat-ldirectord-1.2.3-2.rh.el.3.0

In haresource (without crm), I have configurations:

****************************************
SMSCONV11 \
        172.16.1.80 \
        172.16.1.81 \
        ldirectord::/etc/ha.d/ldirectord.cf

SMSCONV11 interopOB1

SMSCONV12 interopOB2
****************************************

In a situation the heartbeat is not running on SMSCONV12, I tried to
start heartbeart on SMSCONV11, but in /var/log/message, it seems the
process stucked after bring up interopOB2,

ps -e shows ResourceManager still waiting for sth:

And then it never carry on to start interopOB1 and ldirectord on
SMSCONV11. I previously have the same problem with heartbeat version
1.2.3, but someone told it has been fixed in 1.2.4, since I can't get
1.2.4's rpms for RH EL3, so I upgraded to heartbeat 2.0.2.

Is it a known bug for heartbeat 2.0.2 as well? How can I fix it or if
I have configured something wrongly?

Your help is highly appreciated!!
