Cloud Foundry app logs error on success

Question

I'm getting this error in my bluemix logs allot.

[APP/PROC/WEB/0] ERR XXX.XXX.XXX.XXX - - [date] "GET / HTTP/1.1" 200 -

What does it mean? It seems to indicate that i'm getting a 200 response and the actual site works, but why is this showing up as an error?

Thanks.

I had asked that myself some time ago and then wrote a blog entry about it. Basically the ERR denotes that the information is coming from stderr. An OUT means the source is stdout. It cloud be that your app and its modules are configured to write the output to stderr and thus you see it.
