Symptoms:
SDL TMS would sometimes send tasks to Recovery at the Routing step because of database deadlocks.

Explanation:
This issue was caused by a custom workflow step which was changing the active workflow for many tasks concurrently. Consequently, this resulted in database deadlocks.

Resolution:
The stored procedure handling the setting of the active workflow has been optimized to eliminate the possibility of getting deadlocks during its execution.

SDL-hosted customers should contact SDL Support to arrange for this hotfix to be deployed.

Customers who host SDL TMS themselves should download the installer for SDLTMS11.4.0 Hotfix for CRQ-4774.exe from the following FTP site: ftp://sdlpatches:5dlpatch35@ftp-emea.sdlproducts.com/SDL TMS/11.4/Hotfix/
