Debug "Header is too large" error on prod

[php-coder]

Time to time, I see the following messages in the logs:

2017-06-06 03:08:13.799  WARN 8332 --- [qtp825249556-126] org.eclipse.jetty.http.HttpParser        : Header is too large >1024
2017-06-06 03:08:13.809  WARN 8332 --- [qtp825249556-126] org.eclipse.jetty.http.HttpParser        : badMessage: 413 for HttpChannelOverHttp@6bbea7c5{r=0,c=false,a=IDLE,uri=/image/130}

need to debug what has happened.

Looks like this logging not helpful:

Looks like this error occurs from nowhere and it doesn't relate to incoming request.
