This article addresses the case where a Flexible PIC Concentrator (FPC) and/or Dense Port Concentrator (DPC) reboot occurs, and a core dump containing the backtrace item ddr_sdram_periodic is generated. If SDRAM errors appear in the NVRAM output, then this is most likely a hardware issue. An RMA is recommended. An FPC/DPC rebooted and generated a core dump. The backtrace of … [Read more...]
