tempdb database grows so large that it runs out of disk space. What causes this
and how can I prevent it?
tempdb is a system database and acts as a global resource which is available to
all users connected to SQL Server. It is used to store user objects, internal
objects and version stores. Tempdb fills up if there is not much free disk
space or the data base has a unreasonably low maximum size for database growth.
Tempdb call fill up by:
-
Sorting that needs more memory than what’s allocated to SQL Server.
-
Large result sets including UNIONS, ORDERBY, GROUPBY clauses.
-
Orphaned objects
Tips to prevent tempdb to go out of space:
-
Set tempdb to auto grow.
-
Ensure the disk has enough free space
-
Set it’s initial size reasonably
-
If possible put tempdb on its separate disk.
-
Batch larger and heavy queries
-
Try to write efficient code for all stored procedures, cursors etc.

Most of the times the query design is responsible for increase in size of
tempdb database. The query returns a large amount of rows when no predicate or
where clause is specified. Often, the server database is open to multiple users
to fire queries. This also causes the disk space to run out of memory. To avoid
this, either the number of users can be limited to hit the server or bad
queries should be avoided. Bad queries can be avoided by limiting the size of
tempdb database. It is better to let the users query fail rather than stressing
the server to execute bad queries. The temp database should be ideally
pre-sized. This will avoid it to auto grow when not in use.

-
Mostly a poorly designed query is the reason for causing the tembdb to
increase.
The tempdb database can be used directly via Transact-SQL or indirectly by
ORDER BY or GROUP BY clauses.
-
The query causing the problem should be identified. (Profiler can be used to
capture the data and analyze it)
-
Another reason the tempdb can grow is due to a query returning heavy data.
Usually the WHRE clauses are not specific enough in this case.
-
In cases where the number of queries cannot be controlled, the size of the
tempdb can be set and limited. This causes a bad query to run out of resources
and terminate.
