      Description

      When running Crowd Server 3.0.0, the functionality to detect if there are multiple Crowd instances connected to the same database might trigger a false positive. This will cause the instance to be blocked with a message like

      The Crowd database (database-url) is being updated by another instance. The instance IP is 1.2.3.4. Please make sure all the instances connected to this database are Data Center instances and have clustering enabled.

      Workaround:
      You can set the system property crowd.check.concurrent.instances.interval to 0 to disable the check.

      This can be achieved by changing the CATALINA_OPTS environment variable when running Crowd:

      CATALINA_OPTS=-Dcrowd.check.concurrent.instances.interval=0
