• What is the cause and solution for SAP error message ITS090 - Snapshot information about usage of threads ?

  The SAP error message ITS090, which refers to "Snapshot information about usage of threads," typically indicates an issue related to the performance or resource management of the SAP system, particularly in the context of Internet Transaction Server (ITS) or Web Application Server (WAS). This message is often associated with thread management and can arise due to various reasons.
  Cause:
  
  Thread Overload: The system may be experiencing a high number of concurrent requests, leading to thread exhaustion.
  Configuration Issues: Incorrect configuration settings for thread management in the SAP system can lead to inefficient resource utilization.
  Long-Running Transactions: If there are transactions that take a long time to complete, they can hold onto threads longer than necessary, causing a backlog.
  Memory Issues: Insufficient memory allocation can lead to performance bottlenecks, affecting thread availability.
  System Bugs: There may be bugs in the version of SAP you are using that affect thread management.
  
  Solution:
  
  Monitor Thread Usage: Use transaction codes like SM50 or SM66 to monitor active processes and threads. Identify any long-running processes that may be holding onto threads.
  Adjust Configuration: Review and adjust the configuration settings for the number of threads and processes in the SAP system. This can be done in the instance profile parameters (e.g., rdisp/threads, rdisp/wp_no_dia, etc.).
  Optimize Code: Review custom code or transactions that may be causing long execution times. Optimize them to reduce the load on threads.
  Increase Resources: If the system is consistently under heavy load, consider increasing the hardware resources (CPU, memory) allocated to the SAP instance.
  Patch and Update: Ensure that your SAP system is up to date with the latest patches and updates, as these may contain fixes for known issues related to thread management.
  Load Balancing: If applicable, implement load balancing to distribute the workload more evenly across multiple application servers.
