Are my actual worker threads exceeding the sp_configure ‘max worker threads’ value?






select scheduler_id,current_tasks_count,
current_workers_count,active_workers_count,work_queue_count   
from sys.dm_os_schedulers  
where status = 'Visible Online'
go
select is_preemptive,state,last_wait_type,count(*) as NumWorkers
from sys.dm_os_workers
WHERE last_wait_type IN ('HADR_WORK_QUEUE','HADR_NOTIFICATION_DEQUEUE','PREEMPTIVE_HADR_LEASE_MECHANISM')  
Group by state,last_wait_type,is_preemptive   
order by count(*) desc 
go
/*
from this stored procedure check count of "maxworkers" and "WorkersCreated"
*/
Sp_server_diagnostics

select last_wait_type, count(*) as NumRequests from sys.dm_exec_requests   
group by last_wait_type   
order by count(*) desc
go
select  is_user_process,count(*) as RequestCount from sys.dm_exec_sessions s   
inner join sys.dm_exec_requests r   
on s.session_id = r.session_id   
group by is_user_process

I got this error in one of my client's production environment, this type of issues might come up when we are not properly updating statistics.
