Do you have any custom code anywhere? And when does this occur? Solr cores are
only closed when Solr is shutting down or, in the case of transient cores, one
of them is being evicted from memory. Are you using transient cores?
No one else has reported this, so my first guess is that you are somehow doing
something custom, but that’s a guess.
