How to keep the process instance in the same point after RHPAM restart?

Issue

• In the middle of a process execution, the PAM execution server crashed. When the server is restarted, will the process instances that were running when the server crashed start continuing automatically or do we need to manually restart the process instances? How can we ensure that process instances that were partially completed before the server-crash continue from the correct point in the process and not restart from the beginning of the process?
