Andy on "[Plugin: UpdraftPlus - WordPress Backup and Restoration] wp-cron.php and zip continue running"

It ran last night a bit better, I think. I've put the logfile here: http://pastebin.com/TR97efmJ

I haven't yet swapped the zip off the binary - that will be my next step...
That run last night produced the following zombied processes:

Actually prevented the cron job from "completing". :-(
