[pgpool-general: 124] Problem recovering node

Hello,

I am using pgpool 3.1.1 with pgpoolAdmin 3.1.1 and a streaming master-slave
setup according to the howto (
http://www.pgpool.net/pgpool-web/contrib_docs/simple_sr_setting2/index.html
).

When both nodes are up, everything works fine, gets replicated, no
problems. pgpool runs on server0. When server0 is master, and I shut it
down, server1 becomes master without any problems. I can access the
webinterface of pgpoolAdmin and see that server0 is down. I can recover it
without any problems. But when server1 is master (server0 slave) and I shut
down server1, I can see that server0 becomes the master. But I cannot see
the nodes in pgpoolAdmin status page anymore, it just hangs forever.
Sometimes when I wait a looong time, it does display server0 as the master,
but this happens rarely.

Any idea what this can be?
