I eventually found the problem : with a kill -HUP
beoserv just rereads the list of MAC addresses and
does not allocate more nodes than when launched the first
time. I had to restart beoserv, thus killing the jobs
being processed on the older nodes. This should maybe
be fixed or included in the documentation ; or at least,
maybe declaring at first more nodes than present in the cluster...
