instances?
Hi Mauro,
If you are running your application under windows you might have the same
problem i had few months ago.
My problem was due to an windows OS limitation on the number of sockets that
can be open at any one time.
On windows the FD_SETSIZE parameter have a default value of 64, so with that
default value,
the server can only handle 64/2 = 32 clients at the same time ( 2 sockets
per client). So to solve my problem i only had to increase the FD_SETSIZE
parameter.
Hope that this information did help you.

Thank you for your fast response.
I'm not reading data from files; my application receives data from a custom
HW and uses Live555 to receive the streams from the HW and offer them through
RSTPServer. I found that the 36 input streams are well received. The first 32
(and just now I reached 34) clients are well accepted. Using TcpView, I see 210
active sockets, ie. (36 in + 34 out)*(1 rtp + 2 UDP) = 210; besides there is
one RTP socket opened and closed due to the 35th client's periodic attempt to
get its stream.
For your information, I have 37 environments, each with its own doEventLoop
thread; one is for the unique RTSPServer instance and the others for the 36
RTSPClient instances. The RSTPServer has 36 session instances, which are fed
via circular buffer (a new DeviceSource).
Do you think I run into an "max open socket" limit (even if 210 is much less
than 65535)?
Thank you very much,
Renato MAURO

I wrote an RTSPServer application using Live555. I have 36 different
sessions, each with one video subsession. It works and have one limit only: it
seems to be impossible to serve more than 32 client requests at a time(no
difference between 32 clients on the same session or one client on 32 out of 36
sessions). On the client side, the , rtspClient->sendOptionsCmd(url) methos
fails.
I will debug my application more deeply in order to understand where,
on the server side, the client request is not satisfied; by now my "high level
analysis" question is: is there any max limit for RTSPClientSession instances?
Not in our code; however, you may have run into a limit - in your operating
system - of how many open files it can have (for each process) at a time.
Depending on your OS, there should be a way to increase that limit.
