Hi everyone,

I am experiencing strange problems on a two node cluster. The nodes are virtual 
machines on a XEN 5.6 SP2 host. I have set up a simple cluster with no 
resources defined. After I setup the configuration and commit it to the cluster 
the message  [TOTEM ] FAILED TO RECEIVE comes up and shortly after that the AIS 
connection is lost and I cannot access the crm anymore.

Here is the output:

Sep 21 13:41:04 node1 cib: [11499]: info: cib_replace_notify: Replaced: 0.5.23 
-> 0.6.1 from <null>

This is the configuration, nothing fancy here:

node node1
node node2
property $id="cib-bootstrap-options" \
        dc-version="1.1.5-5bd2b9154d7d9f86d7f56fe0a74072a5a6590c60" \
        cluster-infrastructure="openais" \
        expected-quorum-votes="2" \
        stonith-enabled="false" \
        no-quorum-policy="ignore"
rsc_defaults $id="rsc-options" \
        resource-stickiness="100"

I am running corosync 1.3.1, openais 1.1.4 and pacemaker 1.1.5.

I see this a lot too on a different cluster on this XEN host.

What does "[TOTEM ] FAILED TO RECEIVE" exactly mean and why does the cluster 
get so unstable after that?

Thank you,
Sascha
