I create service in DI:

$di->setShared('Company\TariffService', [
    'className' => 'XXX\Models\Services\Service\Company\TariffService',
    'arguments' => [
        [
            'type' => 'service',
            'name' => 'Company\TariffRepository',
        ],
        ...
    ]
]);

It works perfect until I set 11 arguments, it such situation I got Connection Reset/ERR_EMPTY_RESPONSE. I got errors only when call this service:
$this->getDI()->get('Company\TariffService');
How can I debug it?

If using php-fpm(possibly you need to source something too like in apache below).

apt-get install gdb
service stop php5-fpm/php7.0-fpm(or whatver other name)
gdb php5-fpm/php7.0-fpm
// run -X, not sure if it's needed or not

if you are using apache2 php handler:

service apache2 stop
source /etc/apache2/envvars
gdb apache2
run -X

refresh your browser
it should tell you in gdb that execution stoped unexpectedly or something, write bt and post result of it here

Connection reset most likely means seg fault or something similar, if this don't work then just check https://bugs.php.net/bugs-generating-backtrace.php here to how generate backtrace.

Also you possibly have already somewhere core dump. Then just do gdb <whatever process regenreated it> <path to core dump> and write bt

The 2.1.x branch is not longer supported. Could you please try v3?

@sergeyklay @Jurigag ok, it works on v3 and PHP7. I created repo to reproduce this error: https://github.com/Zaszczyk/vokuro. It is needed to run indexAction in indexController.
