RT235 - Details

• The SAP error message RT235 indicates that there are insufficient free slots in the shared memory segments for Monitoring and Threshold Events (MTE). This typically occurs when the number of MTEs being monitored exceeds the available slots in the shared memory.
  
  Cause:
  
  Insufficient Memory Allocation: The shared memory segments allocated for MTEs are not sufficient to handle the current load.
  High Number of MTEs: The system is monitoring more MTEs than the configured slots can accommodate.
  
  Configuration Issues: The parameters for shared memory allocation may not be set correctly in the SAP system.
  
  
  Solution:
  
  
  Increase Shared Memory Allocation:
  
  You can increase the number of slots available for MTEs by adjusting the relevant parameters in the SAP system.
  Use transaction code RZ10 to modify the instance profile parameters. Look for parameters related to shared memory, such as rdisp/memory or rdisp/Shared_Memory.
  You may need to increase the rdisp/memory parameter to allocate more memory for MTEs.
