It looks like someone is asking to read a file from your conf directory and the file isn't there. What is the URL associated with this error?
This is probably not something to be concerned about since it isn't related to Solr running, no more disturbing than throwing a syntax error. That said, I'd like to understand why it's being thrown because it's quite odd.
