Possible chef server issue with node search

ohai chefs,

we have a really weird behaviour on our chef server v.11.0.8-1.

Searches for a specific node return two different nodes:
$ knife ssh ‘name:tst-bukews.sicofe.csi.it’ ‘hostname’ -x root
tst-wsobuke1.sicofe.csi.it tst-wsobuke1
tst-bukews.sicofe.csi.it tst-bukews

Even after re-indexing solr (and also physically removing its index data)
the problem persists.

Here you can see Solr signaling two hits (from
/var/log/chef-server/chef-solr/current):

2013-12-19_17:34:13.33948 INFO: [] webapp=/solr path=/select
params={sort=X_CHEF_id_CHEF_X+asc&indent=off&start=0&q=content:name__%
3D__tst-bukews.sicofe.csi.it&wt=json&fq=%2BX_CHEF_database_CHEF_X:chef_00000000000000000000000000000000+%2BX_CHEF_type_CHEF_X:node&rows=1000}
hits=2 status=0 QTime=0

We also tried to take a peek at the DB and the two nodes appear to be
different (see details below).

The only remaining option we can come up with seems to be deleting and
re-creating those nodes…

Any suggestion?

Thanks,
Marco
