2019-02-10 23:15:29.635 [ERROR] [ersey.server.ServerRuntime$Responder] - An I/O error has occurred while writing a response message entity to the container output stream.
This error seems due to an issue with UIs, in my case, accessing OH through the ios app reliable produces this error for a long time. there are quite a few threads in this forum on this…bottom line, you can safely ignore this.
Your influx warning however seem to indicate that your integration with influxDB does have troubles. You will need to check your items whether this is still a problem for you.
Sometimes when you change a lot, it helps to restart OH2, on linux:
sudo service openhab2 stop
sudo openhab-cli clean-cache #(answer with yes)
sudo service openhab2 start
And wait for a few minutes for everything to come back online.
You did not say what version of OH you are running, the above assumes that you are running OH2
