Hi Reto
If it is only an error that occurs from time to time than it can not
be related to a faulty configuration. Because of that I had a short
look at the code that loads/updates/store this configuration.
Principally the loading of the configuration is not thread save. But
loading only occurs once if the a new SolrCore is loaded.
So triggering this would require a lot things:
* it can only appear of a new SolrCore was bound (e.g. after
activation OR if you update the "{core}.solrindex.zip" file in the
/datafiles folder" and the SolrCore with the new data replaces the
old.
* it would require two concurrent threads to request the SolrYard
So if you use multiple threads and this error appears shortly after
startup or an update to the index, than this might be the reason.
can you please check that
best
