IllegalStateException: Committed; Executed before 500 org.eclipse.jetty.io.EofException

I am getting this error below when I checked the jetty logs. From the posts on these sites, it seems that the tanning salon's response was too slow for the client and she is trying to send a response to someone who no longer listens to him.

Please let me know if anyone has any idea about this. Thanks in advance.
