I have an S3 sync which is continuously showing the same error

Activity with activityType='JobFailure' failed: 'Activity task timed out'. scheduledEventId=1944, startedEventId=1945, activityId=9ced1588-1404-30ff-9ec6-3cd090e3775d, identity='', retryState=RETRY_STATE_MAXIMUM_ATTEMPTS_REACHED

. When I click "Sync now", I immediately get the error

Failed to start sync: An unknown error occurred. (HTTP 409)

Based on the information provided in the knowledge sources, it appears that you're experiencing a timeout issue with your S3 sync in Airbyte. This is a known issue that has been reported before. Let me provide some insights and potential solutions: 1. Timeout Error: The error message you're seeing indicates that the activity is timing out before it can complete. This is similar to the issue described in [this GitHub issue](https://github.com/airbytehq/airbyte/issues/25955). 2. Possible Solution - Adjust Timeout Settings: One potential solution is to adjust the timeout settings for your Airbyte instance. As mentioned in a forum post, you can try tweaking some timeout variables. The Airbyte documentation provides information on configuring these settings: [Configuring Airbyte - Jobs](https://airbytehq.github.io/operator-guides/configuring-airbyte#jobs) 3. HTTP 409 Error: The "Failed to start sync" error with HTTP 409 status could be related to a conflict in the system, possibly due to the previous failed attempts. 4. Additional Troubleshooting: - Ensure that your S3 credentials and configurations are correct and up-to-date. - Check if there have been any recent changes to your S3 bucket or Airbyte configuration that might be causing this issue. - If possible, try creating a new S3 source connection to see if the issue persists. 5. Version Compatibility: Make sure you're using a compatible version of Airbyte. Some users have reported stability issues after upgrading, as mentioned in [this GitHub issue](https://github.com/airbytehq/airbyte/issues/40546). If adjusting the timeout settings doesn't resolve the issue, you may need to gather more detailed logs and potentially reach out to Airbyte support or community forums for further assistance. The full logs of the sync attempt would be helpful in diagnosing the root cause of the problem.
