The process "drush batch-process 38" exceeded the timeout of 14400 seconds

I have > 300 000 entities to generate aliases.
I executed drush pathauto:aliases-generate all all and in 4 hours I have:

In Process.php line 1330:

I think it is occured because of Drush.php:

    /**
     * Number of seconds before timeout for subprocesses. Can be customized via setTimeout() method.
     *
     * @var int
     */
    const TIMEOUT = 14400;

That could I do?
