# Troubleshooting the analysis

If your SonarQube Server 10.4 analysis errors out.

{% hint style="info" %}
**For AI agents:** You're in the SonarQube Server 10.4 documentation. For a list of all 10.4 pages, see the [SonarQube Server 10.4 page index](https://2155789048-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FL4urx4YsPFYDefLTrxao%2Fuploads%2FlBlJSWAzuhYo7WEorlJX%2Fsonarqube-server-10.4-llms.txt?alt=media). For the whole site, see the [page index](https://docs.sonarsource.com/llms.txt) or the [full text](https://docs.sonarsource.com/llms-full.txt). For another version, replace 10.4 in the URL with that version. The [latest version](https://docs.sonarsource.com/sonarqube-server/) has no version number in its URL.

## Out of memory error <a href="#out-of-memory" id="out-of-memory"></a>

If your analysis errors out with `java.lang.OutOfMemoryError: GC overhead limit exceeded` then it means that your project is too large or too intricate for the scanner to analyze with the default memory allocation. To fix this you’ll want to allocate a larger heap (using `-Xmx[numeric value here]`) to the process running the analysis. Some CI engines may give you an input to specify the necessary values, for instance if you’re using a Maven Build Step in a Jenkins job to run analysis. Otherwise, use Java Options to set a higher value. Note that details of setting Java Options are omitted here because they vary depending on the environment.

## PKIX path building failed <a href="#pkix-path-building-failed" id="pkix-path-building-failed"></a>

If your analysis errors out with `PKIX path building failed` then it means that your SonarQube Server instance is configured with HTTPS and a self-signed SSL certificate (see **Securing the server behind a proxy** in [Operating the server](/sonarqube-server/10.4/setup-and-upgrade/configure-and-operate-a-server/operating-the-server.md)). However, the certificate is not correctly configured in the scanner machine’s JVM. This configuration is outside of SonarQube Server scope. The server certificate is unknown and could not be validated with the provided truststore. To solve the issue, you need to [Installing the server’s self-signed certificate](/sonarqube-server/10.4/analyzing-source-code/scanner-environment/install-self-signed-certificate.md). See [Oracle’s documentation](https://docs.oracle.com/cd/E19830-01/819-4712/ablqw/index.html) for more information.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.sonarsource.com/sonarqube-server/10.4/analyzing-source-code/troubleshooting-the-analysis.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
