500 Server Error - On the Hour, Every Hour

Setup, Configuration and Use Runtime

I just noticed that I’m receiving the following in my OpenHab log…

2017-11-03 20:43:13.330 [WARN ] [org.openhab.io.net.http.HttpUtil    ] - Method failed: HTTP/1.1 500 Internal Server Error

How can I perform additional research to find out what is causing this error? I see HTTP so is this an issue with Jetty?

I’m running on 2.2 SNAPSHOT #1072

In looking at the logs I see a pattern…this seems to happening on the hour, every hour.

2017-11-05 04:51:09.909 [WARN ] [org.openhab.io.net.http.HttpUtil    ] - Method failed: HTTP/1.1 500 Internal Server Error

Any Thoughts??

Assuming you are using the Ecobee binding, it’s a harmless Ecobee token expiration. I get the same errors.

I am using the ecobee binding…thank you!

Wish there was a way to suppress or better correlate to ecobee. When you are looking for issues it’s generic nature makes you want to explore it further.

I think it’s incorrect for org.openhab.io.net.http.HttpUtil to log anything above DEBUG level and I think it might be a regression that it now does. A utility class like HttpUtil does not know whether a 500 HTTP status code is something that warrants a log entry; rather the code using HttpUtil would be in a position to know if it should be logged, and at what level.

I agree. Actually, the ESH version of HttpUtil only logs debug messages, the warning was only left in the 1.x compatibility layer. I have created reduced logging level as the util class cannot judge the severity by kaikreuzer · Pull Request #227 · openhab/openhab-core · GitHub to fix this.
