SAP Work Process enters PRIV Mode- How to resolve this issue?

When you see this kind of issue in SAP world it means the users work process has used up all allocated memory and entered into HEAP Area which usually should not by design. If you really want to resolve this issue with high confidence you should start  understanding how SAP memory is allocated and managed. Here are simple approaches at a higher level.

Approach 1:  Kill such a process in PRIV status 
             Get user confirmation before doing this step

Approach 2:  Request user to self logout of the system and log back in
             This will free-up any held memory

Approach 3:  Reduce the limit on the extended memory (defined in ztta/roll_extension), or increase                       the extended memory (see em/initial_size_MB).
              Also tune abap/heap_area_total params too if needed.
