--- Comment #6 from Chris Collins <chrysalis@chrysalisnet.org> ---
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 slot=
s.

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?=3Dnehalam for the cpu.

src.conf is following


LOADER_ZFS_SUPPORT=3DYES
WITHOUT_GAMES=3Dyes
WITHOUT_SENDMAIL=3Dyes
WITHOUT_I4B=3Dyes
WITHOUT_FLOPPY=3Dyes
WITHOUT_PROFILE=3Dyes
WITHOUT_IPFILTER=3Dyes
WITHOUT_X11=3Dyes
WITHOUT_BLUETOOTH=3Dyes
WITHOUT_CVS=3Dyes
WITHOUT_IPX=3Dyes
WITHOUT_PPP=3Dyes
WITHOUT_WIRELESS=3Dyes
WITHOUT_CTM=3Dyes
WITHOUT_LPR=3Dyes
WITH_EXTRA_TCP_STACKS=3Dyes

# BELOW FOR USERLAND DTRACE
WITH_CTF=3Dyes

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.
