Bug Description
There's a lot of supposition in the title of this bug but its currently my best guess.
In this deployment, I have a number of services running in LXC containers across multiple physical hosts; each service is clustered across three units, all on separate physical hosts, using corosync and pacemaker; when using multicast to support cluster communication, I occasionally see a container drop out of the cluster and use its isolation response (to shutdown all managed services); when using unicast I've not yet see this same problem.
LXC containers are bridged to the main physical network using a linux bridge:
eth0 <-> juju-br0 <-> vethXXX <-> | vethXXX |
All MTU's are standard (1500).
