1.skywalking: v8.5.0

3.kafak-reporter-plugin and kafka-fetcher are turned on
4.Deployed in kubernetes,3 oap, 1 ui
5.Customized tomcat plugin implementation

```java
@Override
public void beforeMethod(EnhancedInstance objInst, Method method, Object[] allArguments, Class<?>[] argumentsTypes,
MethodInterceptResult result) throws Throwable {
Request request = (Request) allArguments[0];
ContextCarrier contextCarrier = new ContextCarrier();
CarrierItem next = contextCarrier.items();
while (next.hasNext()) {
next = next.next();
next.setHeadValue(request.getHeader(next.getHeadKey()));
}
AbstractSpan span = ContextManager.createEntrySpan(request.getRequestURI(), contextCarrier);
// ------------------------------Custom start-------------------------------------------

DistributedTraceId newDistributedTraceId = new NewDistributedTraceId(oldTraceId);
ContextSnapshot contextSnapshot = ContextManager.capture();
this.setFieldValue(contextSnapshot, "traceId", newDistributedTraceId);
this.setFieldValue(contextSnapshot, "traceSegmentId", "X" + contextSnapshot.getTraceSegmentId());
ContextManager.continued(contextSnapshot);
}

Tags.URL.set(span, request.getRequestURL().toString());
Tags.HTTP.METHOD.set(span, request.getMethod());
span.setComponent(ComponentsDefine.TOMCAT);
SpanLayer.asHttp(span);
if (TomcatPluginConfig.Plugin.Tomcat.COLLECT_HTTP_PARAMS) {
collectHttpParam(request, span);
}
}

super(traceId);
}
}
```
- Which company or project?
- What happened?
After the cluster is installed successfully, there is no problem with a small amount of access data. After increasing the amount of access data, it is found that there is no response to the query today.

All you mentioned, we have documents to mention that. I can't see what is the point. You should understand, the community is a place to discuss tech and find a solution, rather than a place to provide diagnose service.
Unless you have some specific questions, I don't think this is a valid question.

@wu-sheng
When using 8.1(**But did not modify the custom code**), the cluster is unavailable after running for a period of time, and then I made a part of the transformation
1. There is a problem with the kubernetes cluster deployment mode,
Solution: --set oap.env.SW_CLUSTER=kubernetes
2. There are some error messages such as queue accumulation in the backend, which may be caused by a relatively large amount of data
Solution: kafak-reporter-plugin and kafka-fetcher are turned on
3. Large amount of data, elasticsearch upgrade configuration
Now use 8.5, and solve the above problems, but skywalking is not available today, ui and oap have no obvious abnormalities

Okay, just now, the cluster can query the results again. For the time being, this problem has not happened, although I don't know the reason.:flushed:

Once you changed codes, they are your reponsibility. Don't ask to a community about your fork.
