Netbackup java console 7.0.1 hung

Hi ,

Could any one please help. I have upgraded master server from 6.5.3 to 7.0 latter to 7.0.1

For administering backup i have installed java console 7.0.1 on one of the window server. But when ever i open java console getting hung cant even close the console.

i have checked setconf  int mem and max mem are ok. aut.conf also checked on Master server and have righ permission.

Master server is linux platform and sitting on DMZ,

Note: The other master server in the DMZ is able to administer using the same java console, that too in linux platform

Could any one find a solution for this?
