Summary :
In SAP environments involving RFC Receiver channels with enabled principal propagation across multiple server nodes, issues may arise due to synchronization conflicts when accessing shared JCO connection resources. Specifically, errors like failure in ClientPool generation, RfcClientPool initialization, and JCO Pool and JCOProperties creation have been observed. The underlying cause is the removal of the common JCO repository on server nodes losing the synchronization race, which prevents metadata access for further RFC connections. A temporary fix involves restarting the RFC Receiver channel, whereas a permanent solution requires applying a suitable patch as per the patch table provided.
