When Glassfish is launched, somtimes launching crash is produced.

glassfishv3\glassfish\bin\startserv.bat
A licensee uses the above batch files to launch a glassfish server.
But they sometimes meets the below error if the server is launched with "startser.bat" after ip address changed.
They get IP address from DHCP server.
In my case there is no problem with floating IP.
Can you tell me which part produces error?
They want to know which part casues this error, and are wondering if it is a bug.
