Importing a large number of subscribers

Tuan
I am trying to import subscribers using the CSV import template. I have proved my csv file works correctly when the file is small. However, I have a file of 288,000 subscribers to import. After about 3,600 the import stops with a white screen with no message. Why is this happening?
1. Is there any sort of restriction on how many users I can import? e.g. PHP processing limit?
2. Is it possible to turn off the email address checking during import?
Thank you

Hello James

That depends on your server settings (memory limit and max_execute time)

However, I believe none of the system could import that large number of records. You should split it into smaller files.

Maybe each time, you should import only 2000 records (I know, it would take time to split but I am afraid of that's only solution)

The email check you are talking is handled by Joomla (Joomla requires each user to have a valid email), so we could not skip that check

I split the import into files of 2,000 records each. Imports were fine up to a total of 20,000 records then I started getting 504 Gateway Time-out Nginx errors. Siteground increased the Nginx server timeout to 600 seconds and some php variables as it follows:
max_execution_time = 3600
max_input_time = 3600
max_input_vars = 12000
However, I am still getting 504 Gateway Time-out Nginx errors.Should any of these settings be increased further to enable import to function?

Hi James

I don't see memory limit was increased? Maybe you should try to reduce number of records imported each time, for example 100 records each time to see how it works?
