import completed successfully, product data still incomplete

[jan_rijavec]

As already mentioned in subject. We are using default magento import also via administration panel. Process is finished without any issues but some products data is incomplete. Some of them are imported properly but some are missing related/upsell data, some are without qty/stock status etc...
I did reindex but nothing is changed there.

Csv structure is 100% legit because importing 1 line at the time works perfectly.. 
I am wondering how to figure out which server setting limit is preventing default magento import to insert product data in database properly.

Thank you all in advance.

Hi,

Please do check your server timeout limit, and increase the timeout limit, it will work fine

As this occur sometime due to timeout, as its take time to import the products

1. Under Security, in the Admin Session Lifetime (seconds) text box, type the session timeout interval in seconds that you want to use. For example, a value of 1200 sets a timeout interval of 20 minutes.

Thanks
