Problem Note 58675: A "deadlock detected" error occurs in SAS® Workflow Services when you attempt to transition a business object from one workflow state to another
 |  |  |  |  |
In a SAS® solution such as SAS® Model Risk Management or SAS® Enterprise GRC, you might not be able to transition a business object from one workflow state to another. When you edit a business object and click a button to move the object to the next workflow activity, the workflow state might not change. For example, you might see the problem in SAS Model Risk Management when you edit a model review and click Submit to submit the object for review.
This issue might be caused by a deadlock when SAS Workflow Services attempts to remove a timer. When this type of deadlock occurs, the SASWorkflowServices9.4 log file contains the following error:
org.quartz.JobPersistenceException: Couldn't remove trigger: ORA-00060: deadlock detected while waiting for resource
[See nested exception: java.sql.SQLException: ORA-00060: deadlock detected while waiting for resource]
at org.quartz.impl.jdbcjobstore.JobStoreSupport.removeTrigger
You might also see the following error in the SAS Model Risk Management or SAS Enterprise GRC log file:
