That's very very strange! I can't think what might be causing that. The
correct information is that shown by 'cman_tool nodes -a' as that
queries the totem stack to get its information. You can double-check
this with the command

  # lsof -p `pidof aisexec`

But I'm intrigued as to how this has happened. Is it possible you could
post your cluster.conf and also the output of "cman_tool join -d" please?
