TAO 1.4.10 is very old!! Please upgrade to ACE+TAO+CIAO x.5.8 (i.e.,
ACE 5.5.8, TAO 1.5.8, and CIAO 0.5.8), which you can download from
under the heading: "Latest Beta Kit".
The DOC groups at Washington University, UC Irvine, and Vanderbilt
University only provide "best effort" support for non-sponsors for the
latest release, as described in
Thus, if you need more "predictable" help for earlier versions of
ACE+TAO, I recommend that you check out
for a list of companies that will provide you with ACE+TAO commercial
