Re: Cfexecd enhancements

[Bas van der Vlies]

Mark,

 The answer is in this mail I run cfengine 4 times a hour:
  Quarterly     = (  Min00_05 Min15_20 Min30_35 Min45_50  )
  schedule = (  Min00_05 Min15_20 Min30_35 Min45_50 ) 
  IfElapsed = ( 1 )

  With this schedule interval cfagent will run:
    Min00
    Min01
    Min02
    Min03
    Min04 
    Min05

  I thought cfexecd only starts cfagent once in a five minute interval, but
  in my situation this was not true. So that is why i patched cfexecd to make
  sure it only run once in a 5 minute interval!
