How To Fix RT237 - &1 &3 > &2 &3 Number of pages in spool request queue exceeds threshold

SAP Error Message - Details

• Message type: E = Error

• Message class: RT - Monitoring infrastructure MSG and alert texts

• Message number: 237

• Message text: &1 &3 > &2 &3 Number of pages in spool request queue exceeds threshold

What causes this issue?

The spool request takes on output requests from the dispatcher queue.
The requests remain in the queue until the processing of the request is
complete.

How to fix this error?

If this alert was only triggered by a few very large output requests,
and it is not a question of a general overload situation, you can
increase the threshold for this alert. With a general overload situation
(in this case, the number of requests in the spool request queue will
also regularly exhibit values that are too high), we recommend that you
increase throughput by reconfiguring the SAP system.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message RT237 - &1 &3 > &2 &3 Number of pages in spool request queue exceeds threshold ?

  The SAP error message RT237 indicates that the number of pages in the spool request queue has exceeded a predefined threshold. This can lead to performance issues or even prevent new spool requests from being processed. Here’s a breakdown of the cause, potential solutions, and related information for this error:
  Cause:
  
  High Volume of Spool Requests: A large number of spool requests may be generated, often due to batch jobs or reports that produce extensive output.
  Threshold Settings: The system has a configured threshold for the maximum number of pages allowed in the spool queue. When this limit is exceeded, the error is triggered.
  Spool Configuration: The spool configuration settings may not be optimized for the current workload, leading to bottlenecks.
  System Performance Issues: If the system is under heavy load or if there are performance issues, it may not be able to process spool requests efficiently.
  
  Solution:
  
  
  Increase the Threshold: 
  
  You can increase the threshold for the number of pages in the spool request queue. This can be done in the SAP system settings (transaction SPAD).
  Navigate to SPAD > Spool Administration > Spool Parameters and adjust the relevant parameters.
  
  
  
  Monitor and Manage Spool Requests:
  
  Regularly monitor the spool requests using transaction SP01. Identify and delete any unnecessary or old spool requests to free up space.
  Consider scheduling batch jobs or reports during off-peak hours to reduce the load on the spool system.
  
  
  
  Optimize Spool Configuration:
  
  Review the spool configuration settings to ensure they are appropriate for your system's workload. This may include adjusting the number of spool work processes or the maximum number of spool requests allowed.
  
  
  
  Check for System Performance Issues:
  
  Investigate any underlying performance issues in the SAP system that may be affecting spool processing. This could involve checking system resources, database performance, or network issues.
  
  
  
  Consult SAP Notes:
  
  Check for any relevant SAP Notes that may provide additional guidance or patches related to spool management and performance.
