This internal error should not occur. If you can find no direct cause for the error, note all circumstances and contact IBM Informix Technical Support.

Oninit® Troubleshooting Guidance

Reasons / Common Causes

-427 is another error classified as internal and not expected under normal circumstances, in the same family as -392/-426 — the official guidance identifies no specific application-level trigger.

  1. An internal server-side bug triggered by a specific, likely unusual combination of statement structure and data.
  2. A client/driver-level issue interacting badly with the server's parameter-binding mechanism in a way that produces a count mismatch internally.
Solutions / Resolution
  1. Don't expect to encounter this under normal usage, per the official guidance.
  2. If no direct cause can be identified, document all relevant circumstances — the statement being executed, client driver/version, server version, and any other conditions present at the time.
  3. Contact IBM Informix Technical Support with that documentation, per the official guidance, rather than attempting to diagnose or work around it at the application level.
Examples
Documenting the circumstances for a support case
- Exact statement being executed
- Client driver and version
- Server version
- Frequency: one-off or reproducible?
Diagnostic Checks
  1. Confirm whether the error is a one-off or reproducible.
  2. Check the server version against known issues/patches for this specific internal error.
