Well, I found the issue with my server shutting down under high I/O, now I have the opposite problem where the server shuts down when all the drives are spun down.  If one drive is spinning, everything is ok...once every drive is spun down.....the server shuts down "dirty".

 

 

 

 

No idea where to start on this one.

this is my go script

#!/bin/bash
# Start the Management Utility
/usr/local/sbin/emhttp &
/boot/unmenu/uu

cd /boot/packages && find . -name '*.auto_install' -type f -print | sort | xargs -n1 sh -c 

/boot/custom/bin/fix_samba_config.sh

/boot/cache_dirs -w -p 100

cp /boot/custom/etc/syslog.conf /etc/syslog.conf
read PID < /var/run/syslogd.pid
kill -1 ${PID}
dmesg | logger -tdmesg -plocal7.info -i

The main 24pin? 12V power to the motherboard was not fully engaged. Solved.
