tempdb intial size changes dynamically

  • SQL 2008 64-bit.

    Have been having a problem where the inital size of tempdb is changing. What would cause this? I have never seen the intial size change on it's own before but am somewhat new to SQL2k8.

    Here is a brief partial history:

    initial size--------physical db size--------date

    21GB------------ 21.3GB------------6/16

    22.09GB----------? forgot to get-----6/17

    22.2GB-----------? forgot to get-----6/27

    25.012-----------? forgot to get-----7/15

    10MB-------------Resized initial------8/17

    3894MB-----------25GB--------------8/24

    10GB -------------Resized intial-------8/25

    I up'd the intial size as I have some large reindexes that run.

    What in the world is causing the intial to dynamically resize itself?

    Model initial size is 2MB

    :w00t::w00t:

    Thanks

  • query(s) that use temp tables?

  • Yes lots of queries that use temp table. The problem is the INITIAL size in changing.
