Opened: Sep 30, 2024 Severity: 3-Major
The api_svc_gateway process exhibits excessive memory consumption (observed consuming over 8.5GB), leading to system out-of-memory conditions. This triggers the Linux OOM killer which terminates processes and may cause api_svc_gateway core dumps. System becomes unstable due to memory exhaustion.
1. System instability due to memory exhaustion 2. API service gateway becomes unresponsive 3. Tenants fail to register with api_svc_gateway 4. Critical system processes may be terminated by OOM killer 5. System reboot may be required for recovery
The specific conditions that trigger this memory leak have not been definitively identified due to the insufficient field data and the absence of reliable reproduction steps. Based on available system telemetry, potential contributing factors may include: 1. System migrations (particularly iSeries to rSeries platform transitions) 2. Extended operational periods (observed in systems with 84+ days uptime) 3. Specific API service gateway operational patterns
Monitor api_svc_gateway memory consumption using system commands such as top. If an out-of-memory (OOM) condition renders the system unresponsive, perform a system reboot to restore normal operation.
