Issue Description

When a K2 workflow has a loop back line rule, the process instance stays in a waiting state. Using the SourceCode.Workflow.Client API to open the process instance to retrieve a data field value, and then using the Serial Number to finish the Async Server event in the workflow results in deadlock errors.

Error Message

Deadlock errors are visible in the HostServer.log file.
