Mark Miller commented on SOLR-9836:
-----------------------------------

bq.  Is this long enough that it deserves a @Slow annotation?

Yes.

Have you run the full test suite as well yet?

> I have seen several cases where there is a zero-length segments_n file. We haven't identified
the root cause of these issues (possibly a poorly timed crash during replication?) but if
there is another node available then Solr should be able to recover from this situation. Currently,
we log and give up on loading that core, leaving the user to manually intervene.
