IBM's documentation contains the following description of this error:
CTJTD3602E: The Change Manager is still processing. Wait and retry the discovery at a later time.
Explanation: The Change Manager is still running to process recent changes discovered. The discovery cannot be started until the Change Manager completes.
Operator Response: None.
Administrator Response: Allow time for the Change Manager to complete its processing before starting a discovery.
Programmer Response: None.
What we have found is that this condition can possibly occur for at least a couple of different reasons. The two situations we've found have been:
1. There was a deadlock on the database that we had to clear. A "little while" after we cleared the lock, we were able to successfully run a discovery again without receiving the error message.
2. The change manager partially ran, but didn't update the CHANGE_SERVER_STATUS table. Specifically, it left the value of the STATUS column set to 16 for the last discovery. To fix this, we had to run the following SQL:
update DB2TADDM.CHANGE_SERVER_STATUS set status = 17
This updates the STATUS column for all rows in the table. You could limit it with a WHERE clause, but in our case, it was valid as is.
We then needed to stop and restart TADDM, and the error message went away.

We have had this issue too, we have found that if leave it after a couple hours it allows you to run a discovery again.
