Hi all, I dont know where to post this issue, so maybe this forum is not correct. I receive unregularly these error messages in my logtail, but I cannot help myself because I dont know where to search. See my entries. Any Ideas? Many thanks! ```csv 2018-12-08 07:57:22.930 [ERROR] [ersey.server.ServerRuntime$Responder] - An I/O error has occurred while writing a response message entity to the container output stream.

The quick answer; nothing to worry about and nothing you can do about (unless you are a developer); This error occurs when one of the user interfaces tries to do something and it goes wrong; the most common culprit appears to be the iOS app (which for me is causing this error reliably), but other user interfaces reportedly can cause this error too. If you search the forum, you will find that this error is around for a long time, but does not have any impact on functionality. PS: it will help in future to make your title clearer: [How to ask a good question / Help Us Help You](https://community.openhab.org/t/how-to-ask-a-good-question-help-us-help-you/58396) ---
