Access db fails to display data in datagrid after db exceeds 600k

Hi folks.

My access db displays data into my datagrid control as designed until the db
exceeds 600k in size. The data is inserted into the db from my web form aspx
page. It continues to insert data into the db after it reaches 600k but
stops displaying data in my datagrid control after exceeding 600k.

Thanks for any tips on what might be going on.
