system-config-cluster corrupts IP address on Red Hat Enterprize Linux 5.4

Issue

• system-config-cluster corrupts IP address.

• When editing the cluster software, the cluster software had apparently written a correct IP address for a private resource. But upon saving the trailing digit of the IP address had been removed and a wrong subnet was set.

• Created IP as a resource but in my config file it shows two different IPs, for Resource it is showing xxx.xxx.78.32 and for monitor link it is showing xxx.xxx.78.3.

• On exiting the system-config-cluster GUI for the first time, the following traceback appeared.

        File "/usr/share/system-config-cluster/MgmtTab.py", line 235, in onTimer
