Clustering WebLogic Failure

[Bibi]

Hi, I've received this error during start up. It is explaning that the at startup I tried to bind more than once from two or more servers. However, I'm still not certain of the cause of failure. Can anyone explain by looking at the log below what may have caused the error.

We are running WebLogic 8.1

Bibi,

It looks like a conflict for port 8011 and 8012 which are already in use. Also looks like your adminserver url is http://sgbolton.sgp.hp.com:8011 which is port 8011. If it is on the same server where you are trying to start managed server port conflict will happen.
