• What is the cause and solution for SAP error message ITS034 - Number of newly created threads ?

  The SAP error message ITS034, which refers to the "Number of newly created threads," typically occurs in the context of SAP Internet Transaction Server (ITS) or when dealing with SAP Web Application Server (WAS) configurations. This error is related to the management of threads in the application server, which can impact performance and resource allocation.
  Cause:
  The ITS034 error usually indicates that the number of threads created by the server has exceeded a predefined limit. This can happen due to several reasons:
  
  High Load: A sudden increase in user requests or transactions can lead to the creation of more threads than the system can handle.
  Configuration Limits: The server may have a configuration that limits the maximum number of threads, and if this limit is reached, the error will be triggered.
  Resource Exhaustion: Insufficient system resources (CPU, memory) can prevent the server from efficiently managing threads.
  Thread Leaks: Poorly designed applications or transactions that do not release threads properly can lead to thread exhaustion.
  
  Solution:
  To resolve the ITS034 error, consider the following steps:
  
  
  Increase Thread Limit: Review and adjust the configuration settings for the maximum number of threads allowed in the SAP system. This can typically be done in the instance profile parameters (e.g., rdisp/threads).
  
  
  Monitor System Load: Use monitoring tools to analyze the load on the server. If the load is consistently high, consider scaling up your infrastructure or optimizing the application to handle requests more efficiently.
  
  
  Optimize Applications: Review the applications running on the server for any inefficiencies or potential thread leaks. Ensure that all threads are properly released after their tasks are completed.
  
  
  Check System Resources: Ensure that the server has adequate resources (CPU, memory, etc.) to handle the expected load. If necessary, upgrade the hardware or optimize the server configuration.
  
  
  Review Logs: Check the SAP system logs for any additional error messages or warnings that could provide more context about the issue.
  
  
  Consult SAP Notes: Look for relevant SAP Notes or documentation that may provide specific guidance or patches related to this error.
  
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for detailed information on configuring thread management and performance tuning.
  SAP Community: Engage with the SAP Community forums to see if other users have encountered similar issues and what solutions they have implemented.
  Performance Monitoring Tools: Utilize SAP's performance monitoring tools (like ST03N, ST06) to analyze system performance and identify bottlenecks.
  
  By following these steps, you should be able to address the ITS034 error and improve the performance and stability of your SAP environment.
