since you guys are running cluster 3.0.4, please do the following:

1) add <logging debug="on"/> in cluster.conf

<cluster...
<logging debug="on"/>
...

2) reproduce the above scenario, then collect all the logs, from all
daemons, from all nodes from /var/log/cluster (this is upstream default,
check with Debian if they have changed it please).

then I´d like to see your cluster.conf and have a better idea on how a
node is "killed". If cluster.conf contains sensitive data such as
passwords, either blank them or send the file to me only. I´ll keep it
confidential but please do NOT randomly mangle the configuration to hide
bits.

The recovery operation is strictly dependent on different things. The
configuration and the logs should be able to tell us something.

Thanks
Fabio
