SYMPTOMS

The Log Reader Agent may cause 17883 error messages. These 17883 error messages may cause your instance of SQL Server to stop responding:
Error: 17883, Severity: 1, State: 0
server Process 162:0 (0) UMS Context 0x11DE8B68 appears to be non-yielding on Scheduler 1.
To determine if this problem is occurring, view the minidump files that are generated by the 17883 error messages, and then search for the IsXactStartValid function. If you do find the IsXactStartValid function, compare the stack from your minidump file to the Log Reader offender thread stack that is noted in the "More Information" section. If the stacks match, this problem is occurring.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section. This problem was first corrected in Microsoft SQL Server 2000 Service Pack 4.

MORE INFORMATION

This problem is related to timing and may not always occur. This problem is not very common. When the problem occurs, the Log Reader thread encountered a replication error and was about to log an error. Before the Log Reader thread could log the error, the thread had to yield the scheduler where the thread was running to another thread. When the Log Reader thread yields the scheduler, the thread holds on to a spinlock on an internal SQL Server structure named DBTABLE. The DBTABLE structure is critical for the server operation. After the Log Reader thread yields, the Log Reader thread that was holding the spinlock cannot run again for an extended time. The time may depend on what else is running on the server at that time on that scheduler. During this time, no other threads in SQL Server can access the DBTABLE structure, and the threads must wait for the spinlock. When the wait period for the spinlock exceeds 60 seconds, the 17883 error message is triggered. The CPU for SQL Server process is 100 percent because all the threads are spinning and waiting on the DBTABLE spinlock. The CPU utilization may cause the instance of SQL Server to stop responding.
