Dear openHAB Community,
On my CentOs 7 openHAB Dashboard is starting and then stopping in a cycle with a period around 26 secs (process IDs changing; watchdog daemon?)
For the few moments Dashboard is started I can pull it from port 8080 to remote browser successfully
“Stopped Dashboard” after 10 seconds (pretty reliably 10 secs; with or without access from the browser)
I disabled SELinux to see if this has any influence to no avail.
Please accept my apologies, I am out of ideas by now. I read through quite a log of the community posts but did not find anything like the above.
Any help appreciated. Thank you very much!
Robert
