Dear Neha, This is right that your machine was able to handle 110,000 concurrent users. However, about the errors that you got, we need to know what they exactly are. Are they DB-related errors, or about the client load? Would you please send the errors and also check the utilization of the machines when you are running more than 110,000 concurrent users?
