[solved] Rflink flooding the log file

Currently for some reason the rflink plugin is flooding the logs with the following messages:

2017-05-29 20:37:28 ERROR (MainThread) [homeassistant.core] Error doing job: Exception in callback SerialTransport._read_ready()

No changes where made the last couple of days.
Any suggestion ?

Problem was with the power output of the pi.
