[exim] random smtp delay and error

I've been having some problems recently with exim delaying and reporting
errors when sending mail. It seems to last a few hours then all the
failed messages break loose and send. The machine is a development box
running Ubuntu "Edgy Eft" with Exim 4.62-2.

Maybe some insight/help with reading the log is what need.

Thanks,
Steve

Here is a sample of the exim4/mainlog:
