We make use of parallel processing within FME Flow 2023.1. However we are struggling to de-bug issues that intermittently occur in the worker processes. I can see that, whilst running, each worker process has a log file, stored under the parent job log. However, this is deleted when the worker process closes, even if it fails. This makes it very difficult retrospectively diagnose any issues.

In our FME Server 2021 instance, the worker logs are surfaced in the main job log once complete, which is fine, but I can’t identify any setting to control and replicate this behaviour.

Does any one know of a config change that I can make, in FME Flow 2023, to retain these worker logs somehow?

Anyone able to advise on this?


Hi ​@carl.turner,

Unfortunately, this is a bug present in exclusively 2023.x versions of FME Form and Flow. This bug was resolved in 2024.0, so if you can upgrade to a new version you will able to see the worker logs once more.
