| Q | A | |---|---| | Is Error 338 only related to files? | Primarily, but it can also appear when a named pipe, registry key, or SQL Server lock is accessed by another process. The same troubleshooting steps apply. | | Do I need to install any hotfix? | No. The issue is environmental, not a bug in SSIS itself. The official KB article confirms that the current releases (SSIS 2019, SSIS 2022) handle the error gracefully when you implement a retry pattern. | | Can I suppress the error? | Not recommended. Suppressing hides a real concurrency problem. Instead, use the retry loop or redesign the workflow to avoid simultaneous access. | | What if the lock is held by a Windows service (e.g., antivirus)? | Temporarily disable real‑time scanning on the folder, or configure the AV to exclude the staging directory. The KB article lists a few common services that lock files. | | Will the sample package work on Linux (SSIS on Docker)? | The logic is cross‑platform, but the PowerShell script will need to be replaced by a Bash lsof check. The GitHub repo includes a Linux‑compatible variant. | In practice, when you search for “ssis338 link”
