SAP Error Message - Details

• Message type: E = Error

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

• Message number: 602

• Message text: &1 &3 > &2 &3 (15 Min.) No. of incoming packets in LAN exceeds threshold

What causes this issue?

The threshold value for incoming packets per second has been exceeded.
Check if the threshold value is too low and if it is merely a temporary
problem. If this is not the case, too high a data stream is running
through this server.

How to fix this error?

Check the interface and your LAN. You may have to change the topology
in order to avoid local overload situations.

• What is the cause and solution for SAP error message RT602 - &1 &3 > &2 &3 (15 Min.) No. of incoming packets in LAN exceeds threshold ?

  The SAP error message RT602 indicates that the number of incoming packets in the LAN has exceeded a predefined threshold. This can lead to performance issues or network congestion, which can affect the overall functioning of the SAP system.
  Cause:
  
  Network Congestion: High traffic on the network can lead to an excessive number of incoming packets.
  Configuration Issues: The threshold for incoming packets may be set too low for the current network load.
  Malfunctioning Applications: An application or process may be generating an unusually high number of packets.
  Denial of Service (DoS) Attack: In some cases, this could be a sign of a DoS attack where a malicious entity is flooding the network with packets.
  
  Solution:
  
  Monitor Network Traffic: Use network monitoring tools to analyze traffic patterns and identify the source of excessive packets.
  Adjust Threshold Settings: If the threshold is too low for your environment, consider increasing it in the SAP configuration settings.
  Optimize Applications: Review and optimize applications that may be generating excessive network traffic.
  Network Infrastructure: Ensure that your network infrastructure (routers, switches) is capable of handling the current load. Upgrading hardware or optimizing configurations may be necessary.
  Security Measures: Implement security measures to protect against potential DoS attacks, such as firewalls and intrusion detection systems.
  Consult SAP Notes: Check SAP Notes for any specific recommendations or patches related to this error message.
  
  Related Information:
  
  SAP Basis Team: Involve your SAP Basis team to help diagnose and resolve the issue.
  Network Administrators: Collaborate with network administrators to ensure that the network is configured correctly and is capable of handling the expected load.
  Documentation: Refer to SAP documentation for detailed information on network performance and configuration settings.
  Performance Monitoring: Regularly monitor network performance to proactively identify and address potential issues before they lead to errors.
  
  By following these steps, you should be able to identify the root cause of the RT602 error and implement a solution to mitigate the issue.
