MTP TIM has these frequent messages in the TIM log file, "ignored because it is not handled by this worker."
For a MTP TIM, these messages are frequently seen in the timlog.txt files:
Trace: w4: [client_ip]:client_port->[server_ip]:server_port ignored because it is not handled by this worker
- There are 16 worker processes and when a new connection is opened between the client & the web server, then a specific worker starts processing the data packets for that connection.
- The allocated worker will then remain latched to that connection throughout the complete Business Transaction instance.
- All workers will generate the above message when they see packets for a connection that is already allocated to another worker, so this is working as designed and not something to be concerned about.
