Error Received while importing data using Flat File into SQL server

I am trying to import a flat file into SQL Server table and I received an error below. I verified the mappings looks good and around 5million data gets loaded into the table and then it fails. Any help would be greatly appreciated.

• Copying to [dbo].[TABLE1] (Error)

TCP Provider: The semaphore timeout period has expired Try to use Chunks and take a look here for Example. Please also specify how big FlatFile (the bigger one) you are trying to put into SQL Server ?
