When your workflow template contains a Copy Data Object policy in which the source and target data objects are the same, you might encounter issues with SAS Workflow Services. When executing the policy, SAS Workflow Services copies the value of the data object to itself. This copy action generates another invocation of the same policy. As a result, the data object is updated continuously in an endless loop. When the looping condition occurs, you might see one or more of the following problems:
To prevent the issue for new workflow instances, remove the Copy Data Object policy. After you remove the policy and activate the corrected workflow template, you might need to clean up disk space. Follow the instructions in SAS KB0036267, "Increasing numbers of Apache ActiveMQ journal log files in certain SAS® 9.4 Enterprise BI and SAS® Visual Analytics environments fill up disk space."
You might encounter this issue if you use SAS® Anti-Money Laundering and your workflow template is based on the FCFWorkflow template that is provided with the SAS® solution. To fix the template, follow the instructions in SAS Note 62533, "A workflow template in SAS® Anti-Money Laundering causes utilization issues with SAS® Workflow Services and Apache ActiveMQ."
