SQL Server will use all the ram that it thinks it can up to it's max. From
there it will dynamically allocate as it sees fit but it will not release
any back to the OS unless it specifically calls for it. So your behavior
does not seem uncommon. I would hold off rebooting and see if it happens
again. If you are running other apps on the same server you may still see
some completion for ram but you should not starve it.
