Cron Run Wild

Don't know what is going on, hoping someone here recognizes this and has some sort of answer. 

I have a Mac that becomes unresponsive, even with a fresh install of 10.9. Fired up Activity Monitor and that's when I noticed Cron was sucking up all the memory available, and 99.4% of the processor. If I Force Quit cron, the iMac is more responsive, but not great. 

A partial Sophos scan pointed to a Flash installer that was not kosher, but by then the computer was locked up and unresponsive again so I couldn't retrieve any information about it. Restarted the iMac and deleted the offending file, but after restart the same cron going wild happened again. 

Has anyone seen their cron go wild like this, and if so how did you fix it?

  • Never mind.

    Nothing malicious to be found here, just a sloppy programmer who didn't have a clue as to what 'housekeeping' is. 
    Turns out the program was writing a crontab file, but never cleaning up after itself. The crontab file enlarged until
    it was 30 GB in size, with cron running every line in that file. Deleted the program, deleted the crontab and all is 
    now well.
