Title:
friends-dispatcher is a little busy doing data updates on idle systems
Status in “friends” package in Ubuntu:
Fix Released
Bug description:
I've noticed that on an idle system friends-dispatcher is doing writes
to a bunch of files and logs periodically.
install fatrace, cd to / and run it and you will see the activity.
This is what I observed over a 30 minute interval on the ubuntu-touch

Periodic database updates and writes to the log are fine, but if we
see lots of data and metadata writes spaced out over time with a few
minute intervals between them then spinning media such as hard disks
don't really get the opportunity to go into idle and spin down, hence
consuming more power on laptops etc. Perhaps somebody can look into
seeing of the number of writes can be reduced or batched better.
