Smart SAP Assistant

• What is the cause and solution for SAP error message /PF1/MSG_COMM_POLLER008 - Number of processes are more than the Max allowed ( &1 ) ?

  The SAP error message /PF1/MSG_COMM_POLLER008 indicates that the number of processes currently running exceeds the maximum allowed limit set in the system configuration. This typically relates to the communication poller processes in SAP, which are responsible for handling communication between different components of the SAP system.
  Cause:
  
  Configuration Limits: The maximum number of allowed processes for the communication poller is defined in the system configuration. If the number of active processes exceeds this limit, the error will be triggered.
  High Load: A sudden increase in workload or a spike in user activity can lead to more processes being spawned than the configured limit.
  Resource Constraints: Insufficient system resources (CPU, memory) can prevent processes from completing, leading to a backlog and exceeding the limit.
  Improper Shutdown: If processes are not shutting down properly, they may remain active, contributing to the count.
  
  Solution:
  
  
  Increase the Maximum Allowed Processes:
  
  You can increase the maximum number of allowed processes in the SAP system configuration. This is typically done in the instance profile parameters.
  Look for parameters related to the communication poller, such as rdisp/wp_no_dia (for dialog work processes) or specific parameters for the communication poller.
  Adjust the values accordingly and restart the instance for the changes to take effect.
  
  
  
  Monitor and Optimize Workload:
  
  Use transaction codes like SM50 or SM66 to monitor active processes and identify any that are stuck or consuming excessive resources.
  Analyze the workload and optimize any long-running or inefficient processes.
  
  
  
  Check System Resources:
  
  Ensure that the system has adequate resources (CPU, memory, etc.) to handle the expected load. If necessary, consider scaling up the hardware or optimizing the existing configuration.
  
  
  
  Review Logs:
  
  Check the system logs (transaction SM21) for any related errors or warnings that might provide additional context for the issue.
  
  
  
  Restart the Instance:
  
  If the issue persists and you suspect that there are orphaned processes, a restart of the SAP instance may help clear out any stuck processes.
