Import not working after 200 records page 503 error

I’m using the Import Wizard and was trying to import 5,400 Leads into a new install of SuiteCRM. I used the correct CSV file and did a test import of 100 records with success. It appears to timeout after 200 records and sends me to a 503 error page.

I broke some of the Accounts and Contact imports into chunks of 198 records. It worked for about 5 tries and now it doesn’t work at all. Every try sends me to a 503 error page after about a 5 minute time out.

What do I do?

Check your script timeout in php.ini
