WinSyslog Event ID 11042: Write to File action has an invalid output format#

Answer#

The action’s stored output-format value is not supported by the installed product build. The current event is not written by this action.

Event ID: 11042
Severity: Error
Component: Write to File action
Windows Event Log source: AdisconWinSyslog
Available since: 26.07
Message pattern: Invalid file format {format_id} for Write to File action; nothing was written.

Export and back up the affected Write to File action.
Open it in the installed Configuration Client and select a supported output format.
Reload the configuration and write a controlled test event.

Verify file paths, permissions, and free space — Check expansion, existence, ACLs, service-account context, and storage.
Collect an Event ID and neighboring product events — Preserve the complete event and the product events immediately before and after it.
Export configuration and collect a bounded debug log — Create a text configuration export and time-bounded debug capture, then disable debugging.

Confirm that the test event appears in the intended file using the selected format and Event ID 11042 does not recur.

The complete Windows Application Event Log entry and neighboring product events from the same time window.
