STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article. This problem was first corrected in Microsoft SQL Server 2000 Service Pack 4.
MORE INFORMATION
SQL Server 2000 uses spin count synchronization primitives to provide appropriate internal synchronization and access to internal structures.
For more information about spinning synchronization, visit the following Microsoft Web site:
InitializeCriticalSectionAndSpinCount
When the spin count is exceeded, the penalty can result in up to a 5,000-millisecond delay and the status of the server process ID in the sysprocesses table changes to spinloop. A status equal to spinloop indicates that you may be experiencing the problem. This correction reduces the delay to a maximum of 1 millisecond.
Note It is highly unusual to see this situation on a single processor computer.
