Magento - Import hangs/freezes

I'm currently trying to import a csv file of 940 products (1.57mb). When I use Magento v1.5.1.0 Import function (not the Dataflow function), it gives me the "Please wait..." screen and then hangs indefinitely. When I check the product catalog, all 940 products are there with SKU numbers, but that's it. No other product 开发者_开发百科data seems to have been imported.

EDIT: I was successfully able to import after dividing the file up into 3 parts of approximately 300 products. This leads me to believe that the csv file is fine, but the large amount of files is causing some sort of timeout.

I solved this problem by increasing max_execution_time from 30 to 300 in /usr/local/lib/php.ini
