Environment
Release : 11.4
Component : CA Workload Automation System Agent
Cause
Ports to Application server are not open from Agent. If Application server is on port 7500, then that port must be open from Agent host.
Also, check if the OS ephemeral ports are available from the Agent host.
Resolution
Open the Application port from agent machine.
Also, it is likely that agent system was running out of ephemeral ports at that time. When the agent needs to connect to a server port, it needs a temporary port from the system as well. When the ephemeral port is not available, you will get that error message in the transmitter.log.
A reboot of the system may also clear the issue.
