Something is killing / blocking Serviio

Ever since I upgrade to ubuntu 16.04 Serviio will suddenly stop when playing videos. It is usually an hour or so in, and may not happen for a few weeks.
All i can find in any logs around the time of the crash is errors with systemd.
Serviio does not appear to restart. i.e. nothing in the logs.
Not sure if its serviio or not, all i know is serviio disconnects

Any one recognise the errors below ?

Fixed, nothing to do with Serviio. a router was randomly rebooting
