> After this Solr cannot start claiming that some files that are supposed to
> exist in the index do not exist. On one occasion we observed segments file
> not being present.
> We were able to trace this problem to {{SolrCore.cleanupOldIndexDirectories}}
> using wrong index directory as current index because
> {{SolrCore.getNewIndexDir}} could not read proper index directory due to
> reading code receiving interruption exception.

> seems to address the problem. But it should be said that this is more of a
> hot-patch rather than a proper fix.
