Timeout during Symphony download - AWSDEB003I Writing socket Resource temporarily unavailable

A dynamic domain manager is installed. The installation completes successfully. The dynamic domain manager is not linked to the master domain manager.

In the TWSMERGE.log of the master domain manager, the following mailman message is displayed: 
+ ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
+ AWSBCV082I Workstation DDM, Message: AWSDEB003I  Writing socket: 
+ Resource temporarily unavailable.
+ +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
The same problem occurs when installing a backup domain manager or a fault-tolerant agent.

Cause and solution:

In the localopts file of the master domain manager, the mm symphony download timeout is set to 0 minutes.

Correct the problem by setting the mm symphony download timeout to 1 minute.
