Does the third-party library issue a select(2) call?
Is the library prepared to use/create/deal-with fd_set's with more than
256 bits worth of file descriptors?

Fred,
Thanks a lot for the help.
I already use getrlimit/setrlimit to increase the maximum number of
file descriptors. It works well (I can see the number of files opened
with an fstat, it increases as I expect - and believe me, I have set
the limit well beyond what I really need).
It really seems that I'm facing another limit. The problem is that I
use a third-party library and that the listening function of this
library returns no error code but a null "reference" when it fails, so
I can't really determine the reason why it fails. I suspect that it
encounters a limitation because it only happens when I increase the
number of sockets.

Is there a limitation in the number of sockets (BSD or OpenTransport)
that a Mac OS X application can open simultaneously ? sysctl says
kern.ipc.maxsockets=512 : is this the limit ? And is there a way to
increase this limit (OS X refuses to change kern.ipc.maxsockets) ?
Thanks.

You should probably worry first about the maximum number of file
descriptors , 256 by default. You can set this limit with
getrlimit/setrlimit. I seem to recall testing my app in a scenario
that would have used more than 512 sockets, but I could be wrong.
