Hi Rob,
> Thanks for the advice. It took less time to do the upgrade than to find the bug yesterday. Soon TAO 2.5.8 will be running in Antarctica!
Great! Good to hear that you could upgrade fast, through sponsoring we
try to maintain as much platforms as possible making TAO pretty stable
the last decade.
Maybe you are able to share some information about your system? That
could Doug add to http://www.dre.vanderbilt.edu/~schmidt/TAO-users.html
Regards,
Johnny
