"Illegal character 0x7F in state=HEADER_IN_VALUE" warnings in log

Setup, Configuration and Use Runtime

Hello!

I’ve installed openHABian v1.4 with openHAB 2.2 (fresh install, not upgrade). Everything installed by default (except I used “Move root to USB” from openhabian-config). Even before I added some settings (items, rules, sitemaps) I started to see a lot of strange warning in openhab log. Every minute I see “Illegal character 0x7F in state=HEADER_IN_VALUE” warning in log.
I configured openhab, added add-ons, items, rules, etc. Looks like everything works as expected. But log becomes unusable because of these warnings.

Cannot understand what can be wrong, as this problem appeared before I added any configurations. I saw this warning was mentioned in other topics but with no solution and looks like with another context.

Please point me where to look in order to find reason/fix it.

Thank you in advance!

I found the reason for myself.

Thanks @Olymp I’ve found a reason.

This warings i openHAB logs is caused by minidlna server in my network. There is option notify_interval in minidlna config. Its value was 60 seconds. Having played with this option I see direct dependency between it and warnings. And if I shutdown minidna - issue disappears.

For me this is solution - as I actually don’t use minidlna at all. So now my log is clean again.

As a temporary solution change this option in minidlna configuration file /etc/minidlna.conf to some big enought value:

# Notify interval, in seconds.
notify_interval=60

Or as an option - disable minidlna from autostart:

sudo /bin/systemctl disable minidlna

Or simply remove minidlna at all:

sudo apt-get remove minidlna

I replaced it with plex

disable everything you can, all bindings, all the services you have installed, exclude a computer with openHAB from the network. When the problem goes away, connect gradually backwards and see when the problem returns. I was looking for it.
