SQL Server Memory Leakage

Hi All,

I have a Memory Leakage issue on our SQL Server 2008 Windows R2 , When The Re-Indexing of the Database occurs which is at 01.00 am on a daily basis, it eats up the memory and does not relaease it, the usual solution is to reboot the server, is there any other way to the Server to release the memory after the re-indexing other than rebooting the server. SQL Server is also 64 bit and has been capped at 8GB RAM out of 14 GB RAM.

Thanks

Yemi
