The rule triggers an alert when service broker fails to start the activation manager.
Service Broker activation helps applications to scale dynamically to manage the message traffic. In general, an application uses activation if traffic to the service varies unpredictably or if the service must dynamically scale to handle the traffic the service receives.
The Service Broker activation process consists of two steps. First, Service Broker determines whether activation is necessary. Second, Service Broker determines whether activation occurs. Although the exact process differs between internal activation and external activation, the overall concepts involved are the same for either strategy.
In this case, the Service Broker activation manager determined that activation was necessary and tried to start a Service Broker application, but failed to do so.
This error is recorded in the Linux application log as MSSQLSERVER event ID 9701. This could be caused by a lack of memory during server startup. This is probably connected to one or more other hardware or software problems in the computer.
Investigate the Linux application log to find errors caused by other problems.
Diagnose this as you would any low-memory condition. Increase the available memory by removing less critical applications or by adding virtual or physical memory.
Consider the following solutions to increase available memory:
Increase the size of the paging file.
Restart the server with the -g memory_to_reserve option to increase the amount of memory that SQL Server will leave available for memory allocations within the SQL Server process.
Add physical memory.
