• What is the cause and solution for SAP error message CSM_VMC100 - Shared Garbage Collection ?

  The SAP error message CSM_VMC100 related to "Shared Garbage Collection" typically indicates an issue with memory management in the SAP system, particularly in the context of the Java Virtual Machine (JVM) used by SAP NetWeaver or other Java-based SAP applications. This error can occur when the JVM is unable to reclaim memory effectively, leading to performance degradation or application crashes.
  
  Cause:
  
  Memory Leaks: Applications may have memory leaks where objects are not being released properly, causing the heap memory to fill up.
  Insufficient Heap Size: The allocated heap size for the JVM may be too small for the workload, leading to frequent garbage collection cycles.
  
  Configuration Issues: Incorrect JVM parameters or configurations can lead to inefficient garbage collection.
  High Load: A sudden increase in load or usage patterns can lead to increased memory consumption, overwhelming the garbage collection process.
  Long-Running Processes: Long-running processes may hold onto memory longer than necessary, preventing garbage collection from reclaiming that
