SYMPTOM:
Following a scheduled service execution in Strategy Narrowcast Server 9.x - 10.x, duplicate subscription content is received by the subscribers and the following message is seen in the DE logs:
Unexpected Error in FinishTerminating:[Error: 462 Desc: The remote server machine does not exist or is unavailable]. SE will continue terminating.
Note: In this instance a single, non-clustered, Narrowcast Machine is running the Execution Engine and Distribution Manager.
CAUSE:When a Narrowcast System is running it will continually check to see if the Execution Engine is up and running by periodically pinging it. This behavior also holds true in a single non-clustered Narrowcast System. When an Execution Engine does not return the ping, a new execution of the same segment is begun as this would imply that the Execution Engine is down.
The cause for this erroneous behavior is that at times due to increased load or network traffic, the Execution Engine might take more time to reply to the ping message than the value of the governing setting 'Timeout for Negotiating Ping' setting. By default, the timeout is set to 1000 milliseconds.
ACTION:If this behavior is continually seen it could indicate network or performance issues. But, to prevent this behavior from occurring , the value of the 'Timeout for Negotiation Ping' can be increased:
- Open the Strategy Narrowcast 9.x - 10.x Administration Console.
- Go to the 'System' menu and select 'Set Governing Settings...' under the appropriate system name:
