I can reproduce the segfault, but seemingly not the killed process on 16-cpu LDOM ona T4-2: cpu0 at mainbus0: SPARC-T4 (rev 0.0) @ 2847.862 MHz Segmentation fault (core dumped) 93 Segmentation fault (core dumped) 1616 Segmentation fault (core dumped) 4185 etc. I don't seem to be able to reproduce on a 4-cpu M3000 cpu0 at core0: FJSV,SPARC64-VII (rev 10.1) @ 2750 MHz cpu0: physical 64K instruction (64 b/l), 64K data (64 b/l), 5120K external (256 b/l)
