Not 100% sure. But I'll go through those scripts over the weekend and look for a list of specific things.
Things like locatedb, logrotate or backup of the RPM database or backup in general are likely candidates. They read a lot of data into page cache and with sufficiently large virtual machines it moves the hot spot through the virtual machine. When you overcommit storage on z/VM enough, you will find z/VM page the same amount that Linux reads and writes during that process. I know of one configuration where we had VM thrash for hours when cron.daily took off at 00:15. If these are useful things you might want to spread it over the night, but quite often they're not really needed at all.
