Greetings
I've been playing with JGroups implementing a quite simple application. Until yesterday, it was warking. Today, without any change I'm aware of I started getting this message when connecting to a channel, no matter the number of nodes (all have the same error and never connect to the group) WARNING: failed to join /224.0.75.75:7500 on lo: java.net.SocketException: No buffer space available My code does just this: System.setProperty("java.net.preferIPv4Stack", "true"); channel = new JChannel(); channel.setReceiver(this); channel.connect(group); Tracing the code, I've found it happends here PlainDatagramSocketImpl.join(InetAddress, NetworkInterface) line: not available [native method] [local variables unavailable] PlainDatagramSocketImpl.joinGroup(SocketAddress, NetworkInterface) line: 196 MulticastSocket.joinGroup(SocketAddress, NetworkInterface) line: 357 TP$DiagnosticsHandler.bindToInterfaces(List<NetworkInterface>, MulticastSocket) line: 1872 TP$DiagnosticsHandler.start() line: 1780 UDP(TP).start() line: 851 UDP.start() line: 229 ProtocolStack.startStack(String, Address) line: 744 JChannel.startStack(String) line: 1763 JChannel.connect(String, boolean) line: 406 JChannel.connect(String) line: 381 Thanks in advance Pablo -- ======================================================================== 0 0 0 Pablo Chacin | Dept. d'Arquitectura de Computadors 0 0 0 e-mail: pchacin@... | UPC-Campus Nord.

I forgot to mention in my previous email that the Draw demo application
doesn't work either, so it doesn't looks like a problem of my application, but maybe a configuration problem. pchacin wrote: > Greetings > > I've been playing with JGroups implementing a quite simple application. > Until yesterday, it was warking.

Disable diagnostics (enable_diagnostics="false") in UDP portion of your
XML configuration file. Most likely you will never use diagnostics anyway!

Looks like this is not a JGroups problem; if you google "no buffer space
available" you find many answers how to fix this issue pchacin wrote: > Greetings > > I've been playing with JGroups implementing a quite simple application. > Until yesterday, it was warking.

That's depend on how you define the problem. First, it happened with
just one process in a JVM with plenty of memory. Second, it happened when the local network doesn't allow ip multicast. Just moving to another network "solved the issue". As Vladimir pointed out, I could get rid of the message after turning diagnostics off in the configuration. I thing that maybe , just maybe, JGropus message is misleading as it wrongly identifies a problem with the ip multicast with a memory issue.
