The user has a setup for OCMC load balancing real-time charging requests to 2 BRM servers. Each BRM server is running 4 CMs for data service, 4 CMs for SMS service and 8 real-time discounting pipelines.
Each CM is configured to connect to the 8 real-time discounting pipelines in load balancing mode.Each real-time discounting pipeline has 24 threads.

Question:How to avoid such errors?
