• What is the cause and solution for SAP error message LM058 - Maximum number of sessions reached ?

  The SAP error message LM058, which states "Maximum number of sessions reached," typically occurs when the number of concurrent user sessions has reached the limit set in the SAP system configuration. This can happen in various scenarios, such as when too many users are logged in at the same time or when there are background processes consuming session resources.
  Causes:
  
  Concurrent User Limit: The system has a predefined limit on the number of concurrent user sessions, which may have been reached.
  Background Jobs: Background jobs or processes that are running may be consuming session resources.
  Session Leaks: Sessions that are not properly terminated can lead to a gradual increase in the number of active sessions.
  Configuration Settings: The configuration settings for the maximum number of sessions may be set too low for the current usage patterns.
  
  Solutions:
  
  
  Increase Maximum Sessions:
  
  You can increase the maximum number of sessions allowed in the SAP system. This can be done by adjusting the parameter rdisp/mshost or rdisp/max_wprun_time in the instance profile.
  Use transaction RZ10 to modify the instance profile and increase the value of the parameter rdisp/max_user_no.

  Review Background Jobs:
  
  Check for any background jobs that may be consuming sessions and optimize or terminate them if necessary.
