    SQL error ID 8179 indicates that a prepared statement could not be found with the specified handle. This error typically occurs in environments where multiple users are accessing the database simultaneously, particularly in applications like Microsoft Dynamics NAV that may involve complex transactions or multiple companies accessing the same resources.

    To resolve this issue, consider the following steps:

    1. Check for Resource Limits: Ensure that the SQL Server is not hitting any resource limits, such as maximum connections or memory usage.
    2. Increase Connection Pooling: If your application allows it, increase the connection pooling settings to handle more simultaneous connections efficiently.
    3. Review Application Logic: Look into the application logic to ensure that prepared statements are being managed correctly and not being prematurely released or not reused as intended.
    4. Update SQL Server: Ensure that your SQL Server is up to date with the latest service packs and updates, as fixes for known issues may be included.
    5. Monitor Application Performance: Use performance monitoring tools to identify any bottlenecks or issues that may be contributing to the error.
    6. Consult Documentation: Refer to Microsoft documentation or support for specific guidance related to Dynamics NAV and SQL Server integration.

    If the issue persists, further investigation into the specific environment and application usage patterns may be necessary to identify the root cause.

    In the SQL Server world there is this concept of "prepared statements" which is used by some applications. You could say that it is a temporary stored procedure. That is, the client first calls sp_prepare to store the statement in SQL Server's memory (nothing is stored on disk). This procedure returns a handle. The client later calls sp_prepexec to actually run the query, using the handle it got back. The client can make multiple calls to sp_prepexec for the same handle, typically passing different parameters. Once the client is finished, it calls sp_unprepare to release the statement.

    Error 8179 suggests that the application is passing a handle that it just has made up. Or it passing a handle after having called sp_prepexec. Another possibility is that the database is in an Availability Group and there is a failover. After the failover, all handles for prepared statements are invalid. A good application should check for this condition and have good retry logic.

    However, it seems from your description that this error appears in a specific function in Navision. Thus, it does not sound like a failover problem, but rather a bug in Navision. Or for that matter a bug in SQL Server, although I would deem that as less likely.

    I think it is difficult for us in this forum to troubleshoot this error, but you would need to open a support case with Microsoft, primarily then with the Navision team. If the Navision team think that SQL Server is at fault, they should talk to the SQL Server people internally, I like to think. (Yes, I see that you say that you have no channel. I'm afraid that without a support contract, it will be difficult to get this resolved.)
