Such as, the start event lost or blocked in some channel? Do you think we should tackle the case where the `end` event comes before the `start` event, (i.e. the `start` and `end` are unordered), or simply abandon the `end` event if there is no `start` event already? ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
