请章博士和各位高手指点------备份服务器上ldirectord启动问题

两台机器CentOS5.2，应用为MySQL cluster，想实现负载和HA，
两台机器的主机名和ip如下：
192.168.100.5 server5.domain
192.168.100.7 server7.domain

现在两台机器都安装了LVS+heartbeat+ldirectord,配置文件如下

ha.cf :

debugfile /var/log/ha-debug
logfile /var/log/ha-log
keepalive 1000ms
deadtime 30
warntime 5
initdead 120
udpport 694
bcast eth3
mcast eth3 225.0.0.1 694 1 0
ucast eth1 192.168.100.7
auto_failback on
node server5.domain
node server7.domain
respawn hacluster /usr/lib64/heartbeat/ipfail
apiauth ipfail gid=haclient uid=hacluster

haresource:

server5.domain \
ldirectord::ldirectord.cf \
LVSSyncDaemonSwap::master \
IPaddr2::192.168.100.20/24/eth1/192.168.100.255

ldirectord.cf:

checktimeout=5
checkinterval=10
autoreload=yes
logfile="/var/log/ldirectord.log"
quiescent=no
virtual=192.168.100.20:3306
real=192.168.100.8:3306 gate
real=192.168.100.9:3306 gate

real=192.168.100.12:3306 gate
real=192.168.100.13:3306 gate
real=192.168.100.14:3306 gate
real=192.168.100.15:3306 gate
service=mysql
scheduler=wrr
protocol=tcp
checkport=3306
checktype=negotiate
login="admin"
passwd="admin"
database="testdatabase"
request="select * from test"

我的问题是：
（1）主服务器(server5)能够正常启动，而从服务器(server7)启动时出现如下提示：

ldirectord stale pid file /var/run/ldirectord.ldirectord.cf.pid for /etc/ha.d/ldirectord.cf

（2）当主服务器关闭的时候，虽然从服务器能够正常接管，但是lirectord无法启动
运行/usr/sbin/ldirectord ldirectord.cf status，出现如下所示：

ldirectord stale pid file /var/run/ldirectord.ldirectord.cf.pid for /etc/ha.d/ldirectord.cf
ldirectord is stopped for /etc/ha.d/ldirectord.cf

此时使用ps查看ldirectord时，发现ldirectord没有启动

附server5关闭时，server7的日志：

这个问题困扰我两个礼拜了，望各位能够不吝赐教！谢谢！
