Cron Jobs Continue to Get Stuck. NEW Installation.

Hey David.

I am having to log in twice a day onto phpMyAdmin to clear the cache on a brand new installation.
My original website, Limitless Life Club's autoresponder essentially stopped working - I would have to login in during each run to clear the cache file.

So I got fed up and just made a brand new installation on a new site I am working on.  Its only been on for about 3 months... and the exact same thing happened.  I don't know what to do.  Here is access to the Log File of today's incident.

Every morning when I check to see the log file, it says waiting for previous cron job to complete, and when I go here...


Thanks in advance for your help.
