Every Clarity customer who uses processes (workflows) should have a process engine maintenance policy that defines how long old processes should be kept. This KB Article provides some guidelines / recommendations in maintaining a process engine.
If too many completed processes are allowed to build up, then this can cause performance problems with accessing the Initiated Processes tab. When there are too many rows in the process tables, it eventually slows down performance. The reason is that the processes that are in an error state are loaded each time the process engine is restarted, further adding to the process load time.
Release: All Supported Releases
