Hi, Desnoyers

       For various reasons, none of the three suggestions you mentioned about reproducing the problem can be achieved easily.
       I am also wonder why commit counter not updated...It seems that the span producers not complete commiting(be killed?hang?)? It‘s very hard to debug all span producers since they are too many...
       So, Can I make lttng-consumer just skip out this subbuffer and try to consume the next subbuffer?
No, it's not that simple. Once this state is reached (e.g. caused by a killed application), just skipping this sub-buffer
will not allow applications to continue using this buffer for tracing until it is destroyed.

Thanks,

Mathieu
