Do you mean the frontend trace render problem?

[kidkidkid]

I see, it seems the span_id is the same.

you can have a try:

I see, it seems the span_id is the same.

how to avoid the span_id is the same??

[flyJia]

def get_multiple_delta_id_generator() -> IDGenerator:
global _id_generator
with _once:
if _id_generator is None:
_id_generator = new_multiple_delta_id_generator(2**63 - 1, 1, 10)
return _id_generator

[flyJia]

你这里加了锁啊，导致创建多次创建span拿的是相同的spanid
