Summary :
All update work processes in a single SAP instance are halted under 'stopped CPIC' status due to a deadlock involving synchronous RFCs (Remote Function Calls). The SM50 diagnosis shows multiple processes in the waiting or stopped state, a result of these RFCs causing a bottleneck in the UPD (Update) processes. This issue arises because the involved RFCs both trigger and wait for updates, but are blocked as they await completion of the triggered updates. To resolve this, increasing the number of DIA (Dialog) work processes to match or exceed the number of non-DIA processes is recommended. Additionally, reassigning RFC execution to servers with more DIA processes may alleviate the problem.
