I am having trouble with some of my R710 servers rebooting.
I am using 7.1 AMD64
I discovered the first issue was hyperthreading so disabled that with machdep.hyperthreading_allowed and that made the system more stable but I am still experiencing unexplained reboots.
I have run the dell diagnostics for 12 hours to test the hardware and it found nothing.
I have configured savecore dumpdev="auto" and dumpdir=/var/crash
I have attempted to force a dump with savecore -vvf
Output
Any ideas I am out of ideas, I see others have experienced this issue but have not found a solution online yet.
