  The SAP error message D4404, which pertains to SAP/OS400 roll management, indicates that the peak number of elements for free user management has been exceeded. This typically occurs in environments where there are many users or sessions being managed, and the system has reached its limit for handling these sessions.

  Check the parameter rdisp/roll_area and rdisp/roll_max in the instance profile and adjust them accordingly.
  
  
  
  Optimize User Sessions:
