Yes, this is with the cronjob removed.  So yes, I think we are fixed until
the problem shows up again. :)  Lets keep our fingers crossed!

btw, you asked earlier how often I was running the cronjob that brough eth2
up and down.  At first I was running it 2 times an hour, after the last
problem yesterday I changed it to run every minute.

Hmm, it seems to be back up.  Yes, I did run the flush cache since it's part
of the script you gave me.
