Skywalking duplicate traceId issue

[llluckyou]

Hi, every:
During the process of integrating Skywalking into my company's project, I encountered the issue of duplicate TraceId. These duplicate TraceId are from different calls, mainly HTTP interfaces, which are relatively scattered in timeline. There were more than ten duplicate traces appearing in about two minutes before and after. I would like to know why this problem occurred. The following image shows these repeated traceIDs:

And This image is a screenshot of the gateway API log within the system. I have processed the privacy section, and it can be seen that there are repeated traceIDs appearing multiple times from different calls

That is usually caused by the incompatibility between gateway plugin and your way of using gateway. Maybe you have some customization or extension of the Spring GW.

You need to review the plugin codes and cross check with your codes.

Spring gateway usage is very complex.

Okay, I'll try to find the problem

Just to add, I found that duplicate traceId cannot display the corresponding link when jumping to the trace, and I suspect there is a correlation between the two

As your UI is that old, maybe your agent is old too. Try the latest as always.

The company project used JDK8, so I used version 8.9.0 of the agent. According to the information I found, this is the latest version that JDK8 can use

There is nothing wrong with JDK8 by using the latest agent. That is the Agent compiling requirement as it needs to support JDK 17 as well. However, the core remains compatible with JDK8.

We documented it very clear. https://skywalking.apache.org/docs/skywalking-java/latest/en/setup/service-agent/java-agent/readme/

Okay, thank you. I will try upgrading to a new version of the agent and oap
