2026-02-21 195040 replication-orchestrator INFO Failures: [ { "failureOrigin" : "destination", "internalMessage" : "Destination process exited with non-zero exit code 3", "externalMessage" : "Something went wrong within the destination connector", "metadata" : { "attemptNumber" : 4, "jobId" : 41, "connector_command" : "write"

The knowledge sources show many similar errors where a sync fails with: •

failureOrigin: "destination"

•

internalMessage: "Destination process exited with non-zero exit code X"

•

externalMessage: "Something went wrong within the destination connector"

However, they do not explain the meaning of a specific non‑zero exit code (like

3

) or give a generic root cause for this message. The actual cause is always inside the destination connector’s own logs, which are not included in the snippets. [replication-orchestrator] From the available information I can only say: • Airbyte is reporting that the destination connector container crashed or exited with error code 3 during the

write

phase of job

41

on attempt

4

. • To understand why, you must inspect the destination connector logs for that job/attempt; the platform log line you pasted is only a high‑level wrapper error. This same pattern appears across multiple issues and always requires looking at the connector’s own stacktrace or error message. [replication-orchestrator; S3 Data Lake] The knowledge sources do not contain enough information to map exit code

3

to a specific problem or fix. You’ll need to: 1. Open the job details for

jobId = 41

and

attemptNumber = 4

. 2. Check the destination logs (not just the replication‑orchestrator line) to find the underlying stacktrace or error message. 3. Use that specific error to troubleshoot or search in the Airbyte docs / issue tracker. If you can share the destination connector type and its detailed logs for that job/attempt, I can try to match them against the existing issues more precisely. 👍 0 button 👎 0 button ℹ️ Tip: Mention @kapa.ai in the thread for follow-ups or DM the app for 1-to-1 help.
