RT604 - Overview

• Message type: E = Error

• Message number: 604

• Message text: &1 &3 > &2 &3 (15 Min.) No. of pages paged in exceeds threshold

What causes this issue?

Paging In occurs when a process requires access to data that is not in
the main memory. The operating system then receives the command to page
in the appropriate page. The requesting process cannot proceed until
this is done.

System Response

In principle, paging always reduces performance. Paging in of pages is,
however, less critical for most operating systems - a page in also
occurs when a program is started, and this does not necessarily lead to
performance problems.
If the paging out of pages is greater than the paging in, the system
increases the size of the paging file - therefore the overload on the
main memory increases.

How to fix this error?

High levels of paging can have the following causes:
Too many processes are running on the server
The main memory is too small for the current demand
You an avoid a high level of paging by taking the following measures:
Better distribution of running processes on various servers
Better distribution of running processes to periods of low load
Install more main memory

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

RT604 - Details

• The SAP error message RT604 indicates that the number of pages paged in exceeds a specified threshold. This typically relates to memory management within the SAP system, particularly in the context of the SAP kernel and the way it handles paging and memory allocation.
  
  Cause:
  The error occurs when the number of pages that have been paged into the system exceeds a predefined limit. This can happen due to several reasons:
  
  High Memory Usage: The application or processes running in the SAP system are consuming more memory than expected, leading to excessive paging.
  
  Configuration Issues: The system may not be optimally configured for the workload it is handling, leading to inefficient memory usage.
  Insufficient Hardware Resources: The underlying hardware may not have enough memory (RAM) to handle the current workload, causing the system to rely on paging.
  Long-running Processes: Certain long-running processes may be consuming memory resources over time, leading to this error.
