I'm running solr 9.10.1 on Ubuntu 24.04.4 LTS server. I just noticed these
errors in the server log file:
2026-07-17 12:59:00.069 WARN (qtp1631119258-30) [] o.e.j.s.HttpChannel

What's causing the "CoreContainer has shut down" error, and how can I fix
it? " systemctl status solr" shows the server running fine.
Thank you,
Scott
