ReportServerTempDB with large size

Hi guys,

I configuredmy reportingserverand automaticallycreatestwo databasesby default.For now,hehasonlytwo reports, whichhappen to bea littleextensive,but thedatabaseReportServerTempDB is alreadywith1.5GBin size,and what I realizedafter a few search on the internet, its sizemay increase.

I was wondering ifthere is anyway to preventthe increase in sizeof the database. Asfound nothingconcrete, I wonderwhatyou guyssuggestedtoo.

Regards
