Why do I get the following warning: org.wso2.carbon.server.admin.module.handler.AuthenticationHandler - Illegal access attempt while trying to authenticate APIKeyValidationService?

In JDK 1.7.0_45, all XML readers share the same XMLSecurityManager and XMLLimitAnalyzer. When the total count of all readers hits the entity expansion limit, which is 64000 by default, the XMLLimitanalyzer's total counter is accumulated and the XMLInputFactory cannot create more readers. If you still want to use update 45 of the JDK, try restarting the server with a higher value assigned to the DentityExpansionLimit.

When I call a REST API, I find that a lot of temporary files are created in my server and they are not cleared. This takes up a lot of space. What should I do?

There might be multiple configuration context objects created per each API invocation. Please check whether your client is creating a configuration context object per each API invocation. Also, configure a HouseKeeping task in the <APIM_HOME>/repository/conf/carbon.xml file to clear the temporary folders. For example.

<HouseKeeping> 
        <AutoStart>true</AutoStart> 
        
        <!-- The interval in *minutes*, between house-keeping runs --> 
        <Interval>10</Interval> 

        <!-- The maximum time in *minutes*, temp files are allowed to live in the system. Files/directories which were modified more than 
         "MaxTempFileLifetime" minutes ago will be removed by the house-keeping task --> 
        <MaxTempFileLifetime>30</MaxTempFileLifetime>
</HouseKeeping>
