[jboss-jira] [JBoss JIRA] Created: (JGRP-1254) Fix NoRouteToHost exception in UDP._send()
Fix NoRouteToHost exception in UDP._send()
------------------------------------------
Key: JGRP-1254
URL: https://jira.jboss.org/browse/JGRP-1254
Project: JGroups
Issue Type: Bug
Reporter: Bela Ban
Assignee: Bela Ban
Fix For: 2.6.18, 2.11.1, 2.12
We did the same test with Weblogic and it is able to reconnect after a network failure.
I had a quick look at the code of JGroups and I think that we can override this limit by a
minor modification. It is not necessary to recreate a socket in case of the raise of an
NoRouteToHostException, we can bind the socket to the interface. I've modified the
code to catch the NoRouteToHostException and now my cluster works well and JBoss and
reconnect properly.
I've modified the _send method of UDP class like this :
org.jgroups.protocols.UDP._send :
private void _send(InetAddress dest, int port, boolean mcast, byte[] data, int offset, int
length) throws Exception {
DatagramPacket packet=new DatagramPacket(data, offset, length, dest, port);
try {
if(mcast) {
if(mcast_send_sockets != null) {
MulticastSocket s;
for(int i=0; i < mcast_send_sockets.length; i++) {
s=mcast_send_sockets[i];
try {
s.send(packet);
}
// solve reconnection issue with Windows
catch(NoRouteToHostException e){
log.warn(e.getMessage() +", reset interface");
s.setInterface(s.getInterface());
}
catch(Exception e) {
log.error("failed sending packet on socket " + s);
}
}
}
else { // DEFAULT path
if(mcast_sock != null) {
try {
mcast_sock.send(packet);
}
// solve reconnection issue with Windows
catch(NoRouteToHostException e){
log.warn(e.getMessage() +", reset interface");
mcast_sock.setInterface(mcast_sock.getInterface());
}
}
}
}
else {
if(sock != null)
sock.send(packet);
}
}
catch(Exception ex) {
throw new Exception("dest=" + dest + ":" + port + "
(" + length + " bytes)", ex);
}
}
