I am not sure whether this is a bug, you should check the reported spans/segments. Generally time gaps could be caused by async processes.

How can I cooperate with you to locate this. My operation is very simple. Query mongodb and send Kafka messages

[wu-sheng]

I don't think I have anything to do.
The data is at your side, the plugin is running in your codes.
You could debug codes to find span's fields and data.

This problem is not inevitable，90% of my requests are corresponding。

Is it related to APM collecting data and reporting OAP？

[wu-sheng]

To be fair, I can't know. You need to find out.
This mostly is relative to an agent plugin. I am not sure.
