To ensure that we have proper version/platform/compiler information,
please make sure you fill out the appropriate problem report form
(PRF), which is in
in older versions of ACE+TAO. Make sure to include this information
when asking any questions about ACE+TAO since otherwise we have to
"guess" what version/platform/compiler/options you've using, which is
very error-prone and slows down our responsiveness. If you don't use
the PRF, therefore, it is less likely that someone from the core
ACE+TAO developer team will be able to answer your question.
Naturally, we encourage and appreciate other members of the ACE+TAO
user community who can respond to questions that they have the answers

There are various ways you could do this. One easy one would be to
subclass from ACE_Acceptor and override the make_svc_handler() method
to keep track of the number of active connections and only create a
new SvcHandler if the number of active connections is below
nConnections_. Naturally, you'd need to define some sort of callback
method in your ACE_Aceptor subclass that your SvcHandler will call
when a connection is closed so that the nConnection_ count is
