I agree it is likely a hardware issue. The system requires either half or full DIMM population, so unfortunately the only stable configuration (w/o hardware replacement) is half memory & cores. But 16 cores and 64GB memory is probably OK for the farm for now, and I will replace the defective module(s) early next year. It's online again, and hopefully remains so: root@gcc102:~# lscpu Architecture: sparc64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Big Endian CPU(s): 128 On-line CPU(s) list: 0-63,128-191 Model name: UltraSparc T3 (Niagara3) Thread(s) per core: 4 <-- actually 8? Core(s) per socket: 16 <-- actually 8? Socket(s): 2 Flags: sun4v Caches (sum of all): L1d: 1 MiB (128 instances) L1i: 2 MiB (128 instances) L2: 768 MiB (128 instances) Pierre, you can feel free to re-enable your cron job. Jacob, thank you for your careful analysis and brainstorming.
