Sleep Problems - "Wake on Scan Offload"

hi all,

i've been having battery drain issues 1 particular 2015 rmbp 13.3".

when laptop being used battery seems fine, when lid closed drain fast. on worst occasion 100% charge went 52% overnight.

running 'syslog | grep -i "wake reason"' in terminal has revealed hundreds of 'wake reason's occurring when computer should asleep.

ideas of how resolve this? or else have problem?

power nap not allowed on battery power in settings. apps open before closing lid of following: airmail, messages, chrome, terminal, sunrise calendar, wunderlist

include snippet of terminal output. there chunks of same stuff other hours of night, did not occur 03:01-04:00.


terminal output:
