Summary :
SAP Note discusses the causes and solutions for OutOfMemoryError associated with permanent generation (permgen) space depletion in the Java Virtual Machine (JVM) utilized by XI/PI Java components. The perm size defined via -XX:MaxPermSize and -XX:PermSize is typically set during installation, but may require adjustment based on system demands such as complex Java mappings, adapters, or dynamically loaded classes. Exhaustion of this space leads to substantial garbage collection and potential system restarts due to memory shortage. Solutions involve increasing the perm size parameter appropriately and monitoring physical memory availability, particularly when scaling up configurations across multiple cluster nodes.
