LidarAccumulator: Buffer full, dropping sweep

I am using version 1.2.400 and I am getting a lot of “LidarAccumulator: Buffer full, dropping sweep” messages in my console (Log). I am using the LidarAccumulator example in async mode. What I am doing wrong?

Is there a faster way to consume this buffer? After some time the app crashes.

Dear tiago.cajahyba,
Could you share the used command and steps to reproduce on our machine
