To expand on Michel's answer, it's a generic test for a format string 
vulnerability in a web server; basically, Nessus probes the target using 
various methods (eg, GET, POST, TRACE, ...) and URIs with format strings.

If Nessus is reporting a hole, then it apparently was able to crash the 
service; if just a warning, it saw a string in a response that looked 
like a 8 digit hex number and such a number was not seen when probing 
for a non-existent page. Setting the debug level to 1 should log some 
info in nessusd.dump showing you what it found for a normal answer and 
from the format string attack.
