An update

I have done several memtester runs all passes.
Removed cpu overclock
memtest86 passes
clang39 stable clang40 segfaults random (all new tests with ccache disabled)
I have swapped out memory sticks same result.
I have tried just using less ram so less slots populated and different slots.

I will test on a physical different system this weekend, possibly friday.

The system was originally FreeBSD 10, updated to FreeBSD 11.0, and then in the
past week to FreeBSD11-STABLE.

make.conf only has cputype?=nehalam for the cpu.

src.conf is following


LOADER_ZFS_SUPPORT=YES
WITHOUT_GAMES=yes
WITHOUT_SENDMAIL=yes
WITHOUT_I4B=yes
WITHOUT_FLOPPY=yes
WITHOUT_PROFILE=yes
WITHOUT_IPFILTER=yes
WITHOUT_X11=yes
WITHOUT_BLUETOOTH=yes
WITHOUT_CVS=yes
WITHOUT_IPX=yes
WITHOUT_PPP=yes
WITHOUT_WIRELESS=yes
WITHOUT_CTM=yes
WITHOUT_LPR=yes
WITH_EXTRA_TCP_STACKS=yes

# BELOW FOR USERLAND DTRACE
WITH_CTF=yes

System runs zfs mirror pool and has a ssd for a SLOG device.

Its not a production server so I am not bothered about downtime and also is ok
for the non redundant ZIL.
