Socket Class Leak

[mbmsit]

Hello all,

After i close an opened socket connection using java.net.Socket class
in linux OS , there are some resources left residing in memory ,
shown as 'can't identify protocol ' in the output of lsof command.

After some time and after connecting and disconnecting many times, this leak causes the system error "Too many open files".

How can I make sure all resources reserved by the opened sockets are released properly?

thanks.

Show us some code around where you open and close the Sockets.
(Please use CODE tags)

Are using an open source JVM or one from Sun? Ubuntu comes with an open source JVM by default, and I had some problems with it. The Sun JVM works fine.

this is my code

try {
				Socket s=new Socket("192.168.0.253",143);
				System.out.println("connect...");
				
				s.close();
				try {
					Thread.sleep(100000);System.out.println("asd");
				} catch (InterruptedException e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				}
			} catch (UnknownHostException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			} catch (IOException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}

this code executes sleep duration (100) seconds ,
in this duration , i detect opened connections by :
"lsof -p 'process number' "
same error is displayed :
"can't identify protocol"

i have installed sun jvm , nothing new.
where is the problem ???
