             Summary: java.lang.IllegalStateException from JanuGraph while purging entities at Atlas
                 Key: ATLAS-4766
                 URL: https://issues.apache.org/jira/browse/ATLAS-4766
             Project: Atlas
          Issue Type: Bug
          Components:  atlas-core
            Reporter: Sidharth Mishra


When attempting to purge approximately 1000 entities in Atlas, an exception stack is encountered in the application.log file -
{code:java}

The issue seems to be inconsistent, as the error can occur for different vertices within the list of 1000, resulting in a failed transaction and rollback. Unfortunately, there is no known workaround for this problem, as even with fewer entities, the error persists.
