Nmap has a rather short limit for how much "extrainfo" it allows.  The
Apache server probably had a bunch of modules and such that caused
Nmap to exceed the limit.  Maybe Nmap should just quietly truncate.
But for now it prints the warning above and skips the extrainfo
field.  One option is to remove the $2 on the template above
(nmap-service-probes line 1132).  Or just ignore that particular
error.  Or pipe Nmap to "grep -v info_tempate".
