Run script in tempdb . Can be used to troubleshoot tempdb space usage problems usually associated with large queries that use a lart amount of space for work tables and work files.
USE tempdb
Go
SELECT t.text,
SUM(internal_objects_alloc_page_count) AS task_internal_objects_alloc_page_count,
SUM(internal_objects_dealloc_page_count) AS task_internal_objects_dealloc_page_count
FROM sys.dm_db_task_space_usage st
JOIN sys.sysprocesses sp
ON sp.spid = st.session_id
CROSS APPLY sys.dm_exec_sql_text(sp.sql_handle) t
GROUP BY t.text
ORDER BY 2 DESC
