Hi,

These are interesting strategies, as I have some similar requirement.

For my boxes which are yum based often I see a hung updates yum process 
that is a few days old, so I am looking for something to go and get 
those, as they cause a miss on the next run of yum in cron.

However the outputs of "ps -ef" and "ps aux" are not entirelely trivial 
to parse, as the "STIME" field seems to rollover from a "00:00" bare 
time of day, to  a "MMMDD" format after 24 hours...

Cheers,
Tom
