The maximum of eight VNAC agents have been started
Explanation: Each uniquely named VNAC agent takes a permanent slot in the VitalSigns Agent Anchor Block (VAAB). The VAAB is maintained until the system is next IPLed. A maximum of eight VNAC agents (by name) may be run on a single z/OS image between IPLs. This agent would be the ninth. The agent is terminated.
Action: If there are eight VNAC agents currently active, you cannot start another. If there are fewer than eight agents running, then there have been eight uniquely named agents started since the last IPL. You can run this agent using the name of an earlier agent that is no longer active. Change the MYNAME parameter on the EXEC statement in the agent procedure and restart the agent.
