Hi Prahlad,
The select count(*) statement is executed internally by the MDO objects when ever they are loaded, copied or any operation is done on/in them. These logs are also visible in the Open SQL monitor screen in NWA.
Which MII version are you on? If you are 14.0 SP1 or above, these calls have been minimized to a great extent.

Tufale Ashai.
