Sending an ubuntu virtual box image to your mail address using wetransfer (uploading right
now). Hope this helps you.
jgroups does not recover properly when using UDP after ifdown / ifup
--------------------------------------------------------------------
Key: JGRP-1944
URL:
https://issues.jboss.org/browse/JGRP-1944
Project: JGroups
Issue Type: Bug
Affects Versions: 3.6.4
Environment: Linux Ubutun 14.04 where the network cards are configured as
bridges:
auto bridge0
iface bridge0 inet dhcp
bridge_ports eth1
bridge_stp off
bridge_fd 0
Reporter: Bram Klein Gunnewiek
Assignee: Bela Ban
Fix For: 3.6.5
Attachments: AutoRecoverMulticast.java
When we bring the interface down and back up in a complete (udp.xml) configuration
everything *seems* to be fine, however multicast traffic from the node that had the
interface brought down is not received by other nodes. The node also doesn't receive
any data from the other nodes. No exceptions are logged. I don't think the previous
test was done correctly by me ... sorry .
When we use TCP + MPING we see the stacktraces we had previously with UDP:

(The exact message differs whether or not the -Djava.net.preferIPv4Stack=true argument is
configured)
A configuration that uses MPING also doesn't recover from ifdown/ifup.
