Hi Sourav,
I faced some problems and dumps and what happened to me in my case was invalid CSV and unicode related.
I made a vbs script to read my original csv file (received from partner) and performed other cleasing, bad data handling...
Based on this vbs which copy a text file converting it to ANSI:
Copy a Unicode File to an ANSI File (Windows)
My suggestion is to you start little trying import only 10 rows and see the results.
A great tool you also can handled text and make text convertions I used is Notepad++, the option to go for scripting is because I had around 6 giga on zip format to load, not only one but many .csv files.
