Did you increase the number of file descriptors that can be used by a single process?

We use Netty 3.2.2 and we are satisfied with communication. We moved to a<br>
Linux server ( Ubuntu 10.04) and for testing created simulation platform<br>
which tries to create clients and communicate with server. When creating<br>
clients up to 500, we have no problem and everything is working fine. But<br>
when adding more than 500 clients ( from 500 to 700 ) the server freezes and<br>
don't add more clients. The server communicated without any problem with<br>
connected clients, but doesn't add new clients. We don't know exactly if the<br>
problem is in the OS or in software. Do you know or can help us with this<br>
problem?<br>
<br>
We are using following Parameters:<br>
<br>
ChannelFactory factory = new NioServerSocketChannelFactory(<br>
Executors.newCachedThreadPool(),<br>
Executors.newCachedThreadPool());<br>
// instance Bootstrap object<br>
bootstrap = new ServerBootstrap(factory);<br>
<br>
bootstrap.setPipelineFactory(new GPSPipelineFactory(listener));<br>
<br>
// set bootstrap propertys<br>
bootstrap.setOption("reuseAddress", true);<br>
bootstrap.setOption("tcpNoDelay", true);<br>
bootstrap.setOption("keepAlive", true);<br>
bootstrap.setOption("receiveBufferSize", BUFFER_SIZE); // 1048576<br>
bootstrap.setOption("sendBufferSize", BUFFER_SIZE);<br>
bootstrap.setOption("oobInline", false);<br>
