Shawn Heisey commented on SOLR-3972:
------------------------------------
I agree with Alexandre. When I was copying from the example, which included
copying the included jetty and creating an init script for it, I looked at the
three extra html files, which ARE included there.
I figured since they were "-extra" they were not necessary. I did look into
their actual content and found it useless, so I didn't copy them to my
installation. That's when I ran into the stacktrace - the 20 cores I had when
I first set it up (deriving from my 3.x config) produced *sixty* of these huge
log entries, even when logging at WARN. Now I have 16 cores on the server and
my workaround has eliminated the error.
If a fix for this issue were implemented (using log.warn()) and I deleted the
empty html files, I would end up with 48 consecutive single log line entries if
I left logging at WARN. If the logging were at INFO (which I believe is the
default), they would probably be scattered throughout the log and not make much
difference in its size. That's actually a good argument for making the message
log at info and not warn.

> If a log entry is warranted at all, it should just be a one-line warning.
