Hmm, this is strange. This is emitted by te datagramsocket's send() method, when a datagram packet is too big (usually bigger than 65K). But your message is small, the payload is *zero* bytes ! Can you do the following ? Go into org.jgroups.protocols.UDP and modify send() (I'm assuming JGroups 2.2.7), see code below. This is already in 2.2.9 (currently in CVS). This should print out the size of the *marshalled* buffer in case of an exception. If this doesn't help, you can always set a breakpoint in this code.
Hope this helps ! void send(Message msg) throws Exception { | IpAddress dest=(IpAddress)msg.getDest(); | byte[] buf=messageToBuffer(msg); | | try { | doSend(buf, dest.getIpAddress(), dest.getPort()); | } | catch(Exception ex) { | StringBuffer sb=new StringBuffer("failed sending message to " + dest); | if(buf == null) | sb.append(", null buffer"); | else | sb.append(", length=" + buf.length + " bytes"); | Exception tmp=new Exception(sb.toString() + buf, ex); | throw tmp; | } | } View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=3889993#3889993 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=3889993 ------------------------------------------------------- SF.Net email is Sponsored by the Better Software Conference & EXPO September 19-22, 2005 * San Francisco, CA * Development Lifecycle Practices Agile & Plan-Driven Development * Managing Projects & Teams * Testing & QA Security * Process Improvement & Measurement * http://www.sqe.com/bsce5sf _______________________________________________ JBoss-user mailing list JBoss-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/jboss-user
