Basically at this point with cpanel as your host panel, you now have a bunch of scripts being ran, if you look at the 1st & 2nd asterisks you will note one is running every 15 minutes, as with your old vhost, they probably had that server set with a larger memory_limit as well. You could tweak the cron times that they run or update the memory_limit
