Ganglia Error Message gmond dead but subsys locked

After I installed ganglia, I restart the gmond service.
it is restart perfectly, But while I check the gmond status,
I got the following error message.

PROBLEM

[root@node6 ~]# /etc/init.d/gmond status
gmond dead but subsys locked
SOLUTION
As per the Ganglia manual document, They suggest we need to add the route 239.2.11.71 for ethernet, try the following command then check it,
#route add -host 239.2.11.71 eth0
To add permanently we need to add the line to the following file
/etc/sysconfig/network-scripts/ifup-route - restart system and service then check it,# /etc/init.d/gmond status
gmond (pid 5243) is running... Error message :gmond dead but subsys locked
