How to stop artisan queue:listen command eating all CPU?

I'm running queue listener with command php artisan queue:listen --sleep=10 --tries=3 on Windows 7 laptop. My computer has 4 core CPU and the process is constantly eating up 25% of my CPU load. I tried increasing sleep parameter, but it doesn't help at all. There are no jobs in the queue. I'm using database queue. How to solve it, my computer is getting very hot.
