How can get the reproduce/test procedure for the vulnerabilities reported by NESSUS?

My NESSUS scanning gives report that there are vulnerabilities in my host, such as:

I expect that the tool should give the detailed http request used that can crash my http server, but it is not included in the report. So I am in difficulty to investigate/remedy this vulnerability.

Please help to suggest how I can figure out the http request used which can crash my server? Can the NESSUS tool have this information provided?
