Summary :
This SAP Note addresses issues with the J2EE Engine versions 6.30/6.40. Users must provide clear, comprehensive descriptions of the problems, including relevant logs, environment details, and configuration data to aid the support team. Support requires specifics such as system version, JDK/SDK version, full J2EE Engine version, and application version affected. Additional data might be necessary depending on the specific problem categorized under headings like crashes, hanging engines, high CPU usage, HTTP issues, TCP or thread exhaustion, and memory problems. The solutions include detailed instructions for collecting and submitting the required information, including file locations and conditions for additional diagnostics such as thread dumps or verbose GC output.
