Ikai,

I understand your response to this post but I'd like to let you know
what I have seen.  I see this error "occasionally" when my site has no
load.  Ie: 0 instances.  For example, in the middle of the night when
no users are on the site my cron runs and I receive this error.  To
prevent this I have created "warmup" cron jobs 1 minute before all my
real cron jobs.  So far this has worked, but sometimes I do see my
"warmup" cron jobs error out with this error.  This leads me to
believe this error can happen on cold starts ?
