Memory leak even with 32gigs server

I have server with 32GB memory.

I try to debug what your plugin do with the server with this code:

add_filter( 'woocommerce_product_tabs', 'woocommerce_product_tabs_xxx', 99 );
function woocommerce_product_tabs_xxx($tabs){

    print_r($tabs);// lets see what woodiscuz add to this hook
    return $tabs;

}

When I turn off your plugin, it only show couple lines of “print_r”
But when your plugin activated it add very very very very huge amount of object to $tabs.
What is that? Even my server cant print all this object and crash in the middle.
