Import Went Bad, Produced Error In Back End

I just imported 206 products into my store and 206 images using separate CSV files for images and products. It seemed to go well but when I try to navigate the products page list in the back end, after a few pages I get the following error: Error[color=#B94A48]Oops, something went wrong (Request-URI Too Large). Please try again.[/color]

Any ideas as to what's causing this problem and how to fix appreciated.

Actually, the import worked but I had not set status to A. The error is indeed an actual problem.
