Session creation fails when a burst of new subscribers. Issue arises when scaling to 2000 subscribers with heavy simultaneous session creation.
Session creation fails, leading to performance degradation and error in session states. Throughput tests might be impacted if subscriber addition is not handled correctly.
Occurs when large burst of simultaneous new subscriber flows while adding new unknown subscribers to PEM. Adding subscribers at a rapid rate exceeds session creation rate capabilities.
Add subscribers at a slow rate, not exceeding 200 connections with unique IPs per second. Ensure subscriber addition happens first at a slow pace. Once subscribers are added, start the traffic and proceed with performance measurements.
