Symptoms:
When running the workflow and task level automatic actions, WS - FTS deadlocks can occur. This happens due to the fact that FTS uses a cluster lock with lock type "TASK" when writing the completion or failure statuses of a filter task.
Resolution:
You can fix this issue by deploying the update to FTS, available on FTP.
If you cannot deploy it, connect to the Customer Support Web Portal and log a case. You need an account to log a case. If you do not have an account, contact your company's SDL Support Account Administrator.
