Thanks for the tips.

I had already put the machine through a memtest and it came though no
problems. It isn't overlocked; the machine reboots even when idle;
nothing running other than standard stuff.

I'm not using any encryption or compression.

The Ubuntu live has been running for nearly 24 hours and that hasn't
rebooted.

I did hit a problem which was that I had to turn off Legacy USB support
in order to use OI, but I can't use the keyboard to select a snapshot
to boot from without legacy USB enabled.

No one has offered a possible explanation as to why the root crontab
was overwritten with that one statement, so I'm starting to conclude
that the OS updates could be a factor.

I've got the latest OI for USB stick so I'm going to use that to mount
the ZFS data set and get the data off.  If it remains stable through
that process then I'll be certain that the OS build has problems.

I'll keep you informed.

Michelle.
