Description Luigi Toscano 2011-11-22 17:05:55 UTC

Description of problem:
The out of the box definition of UNHIBERNATE is:
UNHIBERNATE = MachineLastMatchTime =!= UNDEFINED
Thus all the sleeping machines are woken up after each ROOSTER_INTERVAL (because ROOSTER_UNHIBERNATE=Offline && Unhibernate).

I understand that this value would probably need a tuning in every cluster, but I think that a more reasonable default value would be something like:

Unhibernate = CurrentTime - MachineLastMatchTime < 1200

as described here: 
https://lists.cs.wisc.edu/archive/condor-users/2010-April/msg00063.shtml

This could be maybe changed upstream.
