SQL Server Error 19722, with a severity level of 17, typically indicates that certain internal system limits or errors have been encountered during the execution of a query, procedure, or batch in SQL Server. The specific details of this error code are not officially listed under Microsoft's primary documentation at the time of writing. However, based on general best practices for handling severity level 17 errors and undocumented scenarios like this one, below is an explanation and guidance. This suggests that the issue is related to resource availability or an external factor beyond the immediate user's control. This could involve memory allocation issues, disk I/O problems, insufficient resources on the machine hosting the SQL Server instance(s), lock contention issues, or invalid configuration settings, among other potential causes.
Possible causes:
- Limited temporary database (`tempdb`) space due to large operations involving sorting/joins/truncations.
- Memory pressure-related items affecting query workloads.
- A corrupt execution plan being reused or improper statistics causing inefficiencies.
- System-wide constraints being hit (e.g., too many active connections/processes).
- Internal bugs within SQL Server that may require patching.
