## Errors and Solutions
### Why is my CodeScan update binding getting failed?
If the CodeScan update binding is getting failed, try disabling the VPN and antivirus, then try updating the binding again.
**If the binding successfully updates,** the error occurred due to antivirus blocking CodeScan. Add CodeScan to the list of allowed sites for the antivirus in use.
**If the binding still fails**, raise a [Support Ticket](https://support.autorabit.com/portal/en/home), including the **analyzer logs** and **verbose logs** in the attachment.
### Why did I get the following error during initialization of VM: Could not reserve enough space for xxxKB object heap?
If you are experiencing this error when running a scan, the issue may be with your Java version. **32-bit Java versions** have a lower limit to their heap size. This limit can be as low as **1.6GB** on Windows operating systems.
If you are running a **64-bit** operating system, you will need to upgrade to a **64-bit version of Java**.
You can check whether your Java version is **32** or **64-bit** by using the command: ***java -d64 -version*** in your command prompt or terminal. If you have a **32-bit version of Java** installed, you will get the message:
```
Error: This Java instance does not support a 64-bit JVM.
```
To correct this error, please install the proper Java version.
### Why am I getting the error: java.lang.OutOfMemoryError: GC overhead limit exceeded?
This error can be solved by manually adding a parameter to your Ant environment path variable.
**In Windows:**
```
set ANT_OPTS=%ANT_OPTS% -Xmx2048M
```
**In Linux/OS X:**
```
export ANT_OPTS=$ANT_OPTS -Xmx2048M
```
If the problem persists, please contact [support@autorabit.com](mailto:itservice@autorabit.com).
### Why am I getting the error: Jenkins: java.lang.OutOfMemoryError: Java heap space?
This error can be solved by manually adding a parameter to dedicate memory to the build process.
1. In your Jenkins project, click **Configure**.
2. Scroll down to the **Build** section of the page to the Build Step titled **Invoke Ant** with the fields:
* **Ant Version**: [CodeScan](https://www.codescan.io/) Bundled Ant
* **Targets**: sonar
3. Click on **Advanced**.
4. In the **Java Options** field, add the parameter -**Xmx2000m**. This will assign **2000mb** of memory to you build.
If after increasing the heap space, you get the error:
{% code overflow="wrap" %}
```
Error occurred during initialization of VM Could not reserve enough space for xxxxxxKB object heap
```
{% endcode %}
This usually happens because the JVM you’re running is 32-bit, which can’t allocate very large contiguous memory blocks; install and run a 64-bit Java version (or lower the `-Xmx` value) to resolve the issue.
### Why am I getting a PKIX Path Building failed error?
**Error Code:**
```
javax.net.ssl.SSLHandshakeException:
sun.security.validator.ValidatorException:
PKIX path building failed:
sun.security.provider.certpath.SunCertPathBuilderException:
unable to find valid certification path to requested target.
```
This error occurs when the Java environment does not trust the certificate of the server running your SonarQube™ instance.
To correct this issue, you need to install the server certificate to the Java key.
1. In your browser, to the left of the URL, there is a lock icon (). Click on this icon and a window will pop up.
2. From the window, select **Connection is secure**.
3. Next, select the second option: **`Certificate is valid`**.
4. Go to the **Details** tab and click on **Export**.
5. Rename the certificate (e.g., ***codescan-certificate***), then choose a location and save the certificate.
6. The next process is to install the certificate in the **cacerts** file of the jdk installed in the system using the command line.
**Command:**
> keytool -import **-alias** *{alias-name for the certificate}* **-keystore** *“{path for the cacerts file}”* **-file** *{path where we have save the certificate}*
**Example:**
> keytool -import **-alias** *codescan-certificate* **-keystore** *"C:\Program Files\Java\jdk-11.0.9\lib\security\cacerts"* **-file** *c:/tmp/codescan-certificate.crt*
When adding the certificate, password is required. The password is **`changeit`.**
**Note:**
If adding the certificate as a trusted certificate to the Java Keystore still results in the **PKIX path building failed** error, delete the currently installed certificate from the Java Keystore, export a new certificate, and then attempt a new installation of the certificate.
**Command to list all of the certificates from the Java Keystore:** keytool -list -v **-keystore** *“{path for the cacerts file}”* > /tmp/certs\_list.txt
**Example:** keytool -list -v **-keystore** *“c:\Program Files\Java\jdk-11.0.13\lib\security\cacerts”* > /tmp/certs\_list.txt **Command to delete the certificate:** keytool -delete -noprompt **-alias** *{alias-name for the certificate}* **-keystore** *“{path for the cacerts file}”*
**Example:** keytool -delete -noprompt **-alias** *codescan-certificate* **-keystore** *“c:\Program Files\Java\jdk-11.0.13\lib\security\cacerts”*[ ](https://knowledgebase.autorabit.com/fundamentals/faq/codescan-faqs/codescan-self-hosted-issues/java.lang.outofmemoryerror-gc-overhead-limit-exceeded)
