I am generally self sufficient technically but I have run into errors importing leads with Sugar.

The Windows version worked with about 3700 csv entries but the Linux would go to a blank page. (That is a switch eh?)

I had upped the PHP memory to 20 yet could not import the entries. I eventually cut the list to about 300 entries per import and was successful. However, I seemed to be missing some data in some of the fields and the custom mappings never worked.

Any ideas? I am a techie so a simple direction would be find, I should understand most things about PHP and MySql, Linux etc..
