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

<DIV>>you may have run into a limit - in your operating system - of how
many open files it can have;</DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Thank you for your fast response. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>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. </FONT><FONT face=Arial size=2>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.</FONT></DIV>
<DIV><FONT face=Arial size=2>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).</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Do you think I run into an "max open socket"
limit (even if 210 is much less than 65535)?</FONT></DIV>

<BLOCKQUOTE cite="" type="cite"><FONT face=Arial
size=-1> 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.</FONT></BLOCKQUOTE>
<BLOCKQUOTE cite="" type="cite"><FONT face=Arial

<BLOCKQUOTE cite="" type="cite"><FONT face=Arial
size=-1> 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?</FONT></BLOCKQUOTE>

<DIV>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.</DIV><PRE>-- <BR></PRE>
