SYMPTOMS
In Microsoft SQL Server 2000, when you run a large and complex query plan that uses hash operators, you experience delays when SQL Server 2000 compiles and optimizes the plan for the query. You also receive a 17883 error message in the SQL Server 2000 error log that is similar to the following:

Error: 17883, Severity: 1, State: 0

Process 60:0 (16f0) UMS Context 0x000006FBFEA849F0 appears to be non-yielding on Scheduler 3.

You may experience these symptoms when SQL Server 2000 is running on a 32-bit computer or on a 64-bit computer that has 16 gigabytes (GB) or more GB of physical RAM installed.

For a list of all publicly released SQL Server 2000 Post-Service Pack 3a hotfixes, see the following article in the Microsoft Knowledge Base:

810185 SQL Server 2000 hotfix update for SQL Server 2000 Service Pack 3 and 3a



CAUSE
This problem occurs when a worker thread does not allow the User Mode Scheduling (UMS) scheduler to allocate CPU cycles as expected.
