Buffer underflow and crash on bitrates lower than 256kbps

I have the same issue, but I use external DAC and good internet connection. I assembled my project on esp32-wroom.

here are logs:

Is it memory leak?

Also I added two stations from Zaycev.net and these stations plays smoothly. Maybe, standard station's server are too slow or it depends on the certain region? Or is it memory leak? Or buffer size is too small?
