# Unicorn originally logs backtrace line by line with `exc.backtrace.each { |line| logger.error(line) }`.
# However, that means we get a separate logstash message for each backtrace which isn't what we want. The
# monkey patch here overrides Unicorn's logging of error so that we log the error and backtrace in a
# single message.
