### Bug
SkyWalking:8.0.1
OS: MAC/Linux
JRE: OpenJDK 1.8.0_242/1.8.0_252
- Which company or project?
spring cloud gateway 2.1.5
- What happen?
This problem was not found in the test environment, so I think it may have something to do with concurrency。

This error is totally different case. which plugin causes this need your local work. Check why span can't be closed as expected.
