Tvheadend

Hi@all

im using TVHeadend on a Synology DS109 (DSM 4.2)
Connectted is the Synology via USB to a SkyStar USB HD DVB-S Box.
All is working fine but only the Synology doesn´t go to Hibernation mode (Spin down Harddisk)
I have logged which applikation avoid the Spin down and i found this in the log File:
Dec 16 06:20:00 kernel: [54571.680000] [/etc/localtime] opened by pid 5895 [u:(/usr/local/tvheadend/bin/tvhead), comm:(tvheadend)]

Can i configure anything to avoid this acces during the Hibernation mode?
