iMX6 linux board reboots randomly


iMX6 chip in our customized linux board,
#uname -a
Linux utilite-ubuntu-desktop 3.0.35-cm-fx6-4 #6 SMP Fri May 30 10:33:43 EDT 2014 armv7l armv7l armv7l GNU/Linux

Every once a while board reboots without message, nothing special in linux console, not in /var/loig/syslog.

The problem happens on multiple boards on different times, even midnight when no one is touching the board at all.
Not much activity from our application.

i'm dummy to this kind of issue, where should i get started 1st ?

Thanks !
