But the rollback process was taking longer than what it took to for loading so using process explorer i found out kpid of the same spid in sql server and killed You cannot post EmotIcons. Additional check #2 is targeted at workers with lower utilizations that are probably stuck in an API call or similar activity. A mini-dump is always captured when –T1262 is enabled.

A worker is bound to the request and processes the entire request before handling any other request. When the external activity is complete, the worker returns to the end of the runnable list by calling SwitchNonPreemptive. This allows the 17883 error message and other detection logic to look at accumulated values such as kernel and user mode time and compare the values to elapsed wall clock time. Many of these enhancements have been in place for SQL Server 2005 for several years, so a multitude of test passes have been made, making the SQL Server engine an unlikely cause

SwitchPreemptive would only cause a large number of workers to become stuck generating I/O requests and increasing overall context switching.

In a rare circumstance a worker could run and be properly yielding but not switching contexts because no other work is pending.

Unfortunately there is no way of making this process any faster. This is not the case in SQL Server 7.0 , SQL Server 2000 , or SQL Server 2005. Copyright © 2002-2016 Simple Talk Publishing. The worker is simply placed on the tail of the runnable list and the switch is performed.

If System Idle% is low and Process Utilization% is low, then SQL might not be getting enough CPU cycles. The Detection phase (basic check) declares a nonyielding worker. The first action you should take when experiencing error reports is to apply a newer build of SQL Server that contains known corrections. For example, take a 5-second nonyielding CLR condition and the SQL Server 2005 scheduler quantum target of 4ms.

API calls that allow asynchronous activity (such as ReadFile and WriteFile) are often used to avoid kernel mode transitions and to allow the worker to continue processing, thereby maximizing system resources. An idle scheduler has no meaningful work to perform because of waits and/or because no requests (tasks) are present. This white paper outlines the conditions in which these errors can be reported and what steps the database administrator can take to both understand and remedy these errors.

The following is an example of the SQL Server 2005 17883 error message. The following is an example of the trace flag output. 2005-07-05 08:16:56.38 Server   Scheduler monitor trace:   Scheduler 1 is STALLED 2005-07-05 08:17:01.38 Server   Scheduler monitor trace:   Worker         : 036BA0E8 (pass: 274) The KB mentions these workarounds:Reduce the rate at which you create or drop temporary tables. (This may need extensive code change.)Upgrade to SQL Server 2008. (Unfortunately, not everyone can afford that.)Configure In this case, a dump is not automatically taken, since it is assumed that this condition is caused by an external factor.

Microsoft SQL Server Product Support Services has seen I/O problems lead to 17883 conditions. The Sleep(0) call causes the worker to yield to the scheduler using the hosting interfaces. We also are running that same version of WFX. 0 Cayenne OP Suzanne2324 Apr 7, 2010 at 10:12 UTC I have been with this company for less than SP4 is turning into a bit of a beast.-------Moo. :) franco Constraint Violating Yak Guru Switzerland 255 Posts Posted-02/07/2006: 02:15:06 There is a new FIX for event ID 17883,please

Always check for previous errors first The 17883, 17884, 17887 and 17888 error messages are often symptoms pointing to a problem. Note:  Not all API calls are encapsulated by the switch logic. These versions produce extra diagnostics when errors are detected so that you can better determine the root cause of an error. Each time the heuristic decision is made, details about the decision (either nonyield or yielding) are logged in the SQL Server error log.

SQL Server 2000 SP3 and SP4 In SQL Server 2000 SP3 and SP4, when SchedulerDeadlockCheck cycles through the schedulers looking for 17883 nonyield conditions, it also checks the following core condition. If you use SQL Server 2000 SP3 (8.00.0760) you should strongly consider upgrading to SQL Server 2000 SP4 or SQL Server 2005. Always review previous errors in the SQL Server error log before attempting to determine the root cause of any of these errors as prior errors may be the actual cause of Thread creation time: .

The resource boundary check involves kernel and user mode time comparisons against the elapsed wall clock time. Instead, SQL Server 2005 maintains a preferred scheduler for the connection. Since the introduction of the user mode scheduler and the addition of scheduler health error messages, various misconceptions have arisen. However, starting the SQL Server process with the –T1262 trace flag as a startup parameter instructs SQL Server to generate a mini-dump each time the 17883 error is reported.

Process Utilization %. Yes when you restart the instance of SQL Server it will continue with the rollback process.

The logic for detecting 17883 conditions was changed to the following, thereby removing a rare set of false 17883 reports. You cannot edit your own topics. Further reports of 17883 do not capture the mini-dump. To protect the SQL Server from CLR code which may not yield properly, SchedulerMonitor helps protect the scheduler.

The max worker thread setting is used to assign per-scheduler worker limits to the schedulers. If the tail and the head of the runnable list are one and the same (this worker) then no other worker has current processing needs on this scheduler. The mini-dump is generated only on the first report unless trace flag –T1262 is enabled. Copy and open the SQLDmpr####.mdmp file to the debugging machine or open it (from the File menu, select Open Crash Dump) in the debugger from the remote location.

In the debugger command window, issue the following command. ~~[TID]s where TID is the thread ID from the 17883 message to set the proper thread context. Our weekly integrity checks doubled in completion time after we applied SP4.
