PHP memory exhausted

When trying to create a form with a dropdown with almost 1000 lines, PHP is throwing an error:
PHP Fatal error: Allowed memory size of 536870912 bytes exhausted (tried to allocate 6361670 bytes) in /var/www/html/libraries/joomla/database/driver.php

I think that there is something wrong with the way v6 tries do allocate memory, because using more than 512MB of memory is a bit too much just for text. I remember using Chronoforms v5 for this kind of dropdown and it worked.

Hi flashfs,

Could you please post the list of options you have tried to use in the dropdown field ?

And the error occurs when you save the form or when you try to preview it ?

Best regards

Tested with the same data again and now it worked. Don't know what happened. The problem occurred when saving the form.
