Sounds bad.
I would look in the SQL Server error log, to see if there are any
messages.
If this scenario is happen repeatedly, I would consider open a case
with Microsoft, as this sounds like it could be a problem in SQL Server.
That or some hardware problem.
You should of course also make sure with sp_who2 that there are no
active processes. Particularly, watch the CPUTime column, to see if
there is any suspect.
