I believe I've encountered the same or similar ssh-keyscan problem.
local ssh  - OpenSSH_5.1p1 Debian-5, OpenSSL 0.9.8g 19 Oct 2007
remote ssh - OpenSSH_4.3p2, OpenSSL 0.9.8e-fips-rhel5 01 Jul 2008
The remote server was having "problems": 1) no connection; 2)
connection and key returned; or 3) connection but hanging until remote
time out and
disconnect.  With the latter, ssh-keyscan aborted immediately with
exit-code=255 (see attachment).

I disagree with the original poster in that I think that ssh-keyscan
should continue in all cases except for an internal error.  In our
case, ssh-keyscan is buried several layers deep in wrapper scripts
where it is being fed (today) 3690+ host names.  Per the man pages, I
was expecting it to continue regardless of what the remote servers did
or didn't do.
