Shawn Heisey commented on SOLR-9120:
------------------------------------
This issue seems to have fallen out of notice. I suspect that something
changed in Lucene so that Solr is looking at outdated information, and Solr
just needs to be updated so it looks in a new place for data, or so that it
keeps a previous commit point around for a moment while it gathers information.
If somebody has any idea what I can look for, I am willing to put time into
finding a fix, but I have no idea where to begin right now.
The message can be eliminated from the logs by setting the log level for
LukeRequestHandler (full class name
org.apache.solr.handler.admin.LukeRequestHandler) to ERROR, which can be done
either in the Logging UI or in log4j.properties.
