Error new session was refused due to memory bottleneck sap

A SAP-related error!

The error "New session was refused due to memory bottleneck" typically occurs when the SAP system is experiencing memory constraints, which prevents it from creating a new session. Here are some possible causes and solutions:

Causes:

  1. Insufficient memory allocation: The SAP system may not have enough memory allocated to handle new sessions.
  2. Memory leaks: Memory leaks can occur when SAP programs or modules consume more memory than allocated, leading to a bottleneck.
  3. High load on the system: The system may be experiencing a high load due to a large number of users, complex transactions, or resource-intensive processes.
  4. Inadequate system configuration: The system configuration may not be optimized for the current workload, leading to memory bottlenecks.

Solutions:

  1. Increase memory allocation: Check the SAP system's memory allocation and increase it if necessary. You can do this by adjusting the sapcontrol parameter memsize or by increasing the max_memory value in the sapstart parameter.
  2. Identify and fix memory leaks: Use SAP's built-in tools, such as ST03N or ST03P, to identify memory leaks and fix them by optimizing code or reducing memory consumption.
  3. Optimize system configuration: Review the system configuration and optimize it for the current workload. This may involve adjusting parameters, such as max_connections, max_sessions, or max_memory.
  4. Monitor system performance: Monitor system performance regularly to identify potential issues before they become critical. Use tools like ST03N or ST03P to monitor memory usage and identify bottlenecks.
  5. Consider upgrading to a more powerful system: If the system is experiencing frequent memory bottlenecks, it may be necessary to upgrade to a more powerful system with more memory and processing power.
