The warning message is:

"[warning] Tracer discarded 280625 events between [1334315833.578351009] and
[1334315833.578351380]. You should consider increasing the buffer size."

which states that the tracer did discard the events (not the converter).
But maybe I'm missing your point. What would you recommend to make this
message clearer ?

Thanks,

Mathieu
