Gus Heck commented on SOLR-8349:
--------------------------------
re-applied patch to trunk (no conflicts) and ran tests, and hit this... I had
seen something like this before but I hadn't noted the seed at the time and it
hadn't happened in a while so I assumed it had been fixed by something I did.
Looks a little like it might be the blob store not being ready (SOLR-8772).
This seed seems to reproduce it reliably, though the test passes most of the
time for me. (Ran it 10 times, saw this twice).

> In some cases search components or analysis classes may utilize a large
> dictionary or other in-memory structure. When multiple cores are loaded with
> identical configurations utilizing this large in memory structure, each core
> holds it's own copy in memory. This has been noted in the past and a specific
> case reported in SOLR-3443. This patch provides a generalized capability, and
> if accepted, this capability will then be used to fix SOLR-3443.
