Hi,
Something strange happens when I run caUtils create-ngrams:

There is a PHP warning at beginning of execution.
The percentage increase exceeds 100.0%!
The script terminates with a fatal error.

The script is launched with sudo command.
PHP 7.4.33 (cli) (built: Apr 12 2024 00:02:16) ( NTS )
Here is an extract of execution: (I removed all lines between 15.0% and 97.0%)
