• What is the cause and solution for SAP error message 14305 - Maximum number of failed shared GCs exceeded ?

  The SAP error message "14305 Maximum number of failed shared GCs exceeded" typically indicates that the system has encountered issues with garbage collection (GC) in the context of shared memory management. This error can occur in SAP systems that utilize the Java Virtual Machine (JVM) or in environments where shared memory is managed.
  Cause:
  
  Memory Pressure: The error often arises when the system is under memory pressure, leading to repeated failures in garbage collection attempts.
  Configuration Issues: Incorrect configuration of the JVM or insufficient memory allocation can lead to this error.
  Resource Contention: High contention for shared resources can cause garbage collection to fail repeatedly.
  Long-running Processes: Long-running processes that consume significant memory can lead to increased GC activity and potential failures.
  
  Solution:
  
  Increase Memory Allocation: Review and increase the memory allocation for the JVM. This can be done by adjusting the parameters in the instance profile (e.g., jvm_memory settings).
  Tune Garbage Collection Settings: Adjust the garbage collection settings to optimize performance. This may involve changing the GC algorithm or tuning parameters such as heap size.
  Monitor System Performance: Use monitoring tools to analyze memory usage and GC performance. Identify any long-running processes or memory leaks that may be contributing to the issue.
  Review Configuration: Ensure that the JVM and SAP instance configurations are set correctly. Check for any misconfigurations that could lead to resource contention.
  Restart the Instance: In some cases, a restart of the SAP instance may temporarily resolve the issue, but it is essential to address the underlying cause to prevent recurrence.
  Update Software: Ensure that you are running the latest patches and updates for your SAP system, as newer versions may contain fixes for known issues.
