Please refer to RSA Knowledge Base Article 000030327 -- Artifacts to gather in RSA Identity Governance & Lifecycle to find the location of the aveksaServer.log file for your specific deployment, if you are on a WildFly cluster or a non-WildFly platform. The aveksaServer.log may also be downloaded from the RSA Identity Governance & Lifecycle user interface (Admin > System > Server Nodes tab > under Logs.)

 
Cause
One of the collected attributes contains null characters (NULL). An example of an attribute that always contains a null character is the Microsoft Active Directory objectSid attribute:

Resolution
RSA Identity Governance & Lifecycle Data Collectors do not support collecting attributes that contain NULL characters. Only collect attributes that do not have NULL characters. For example, try using the objectGUID attribute instead of the objectSid attribute as a unique identifier for Microsoft Active Directory objects.
