Cloudera Manager failed to start Activity Monitor

I downloaded CDH 4.5 quick start vm from here. Each service looks good except for below error was seen after I opened Activities tab to view mapreduce activities:

The Activity Monitor server (activitymonitor (localhost)) is unavailable or not responding to connections.

The problem remains after I tried to restart Activity Monitor service, then I found following error message in the log. Can anybody help take a look?

"java.net.BindException: Address already in use" clearly states that port 9999 is already occupied by some other service. You have to check the PID of the service and stop it:

lsof -P | grep LISTEN | grep 9999

use the PID to kill or if you know the service then stop gracefully
