Sorry for the interruption, This error was due to wrong context path mentioned
in solr-jetty-context.xml
<Set name="contextPath"><Property name="hostContext" default="/XXXXXX "/></Set>
And in jetty.xml it was referring /solr. So index was locked.
Thanks,
Srinivas

Hi Shawn,
I did delete the data folder of the core and also did in windows command: solr
stop -all. I see only one solr server is running in this machine which gets
started and stopped when I do so. To confirm, I even copied my folders to
another system and tried there but facing same issue.
In solr-config.xml if I replace <lockType>${solr.lock.type:native}</lockType>
with <lockType>${solr.lock.type:single}</lockType>. It starts without any error.
Please let me know how to find if other servers are running or if it is an
issue with solr 8.4.1 version.
Thanks,
Srinivas

This appears to be saying that the index in that directory is already locked.
Lucene can detect when the index is already locked by the same program that
tries to lock it again, and it will say so when that happens. The message did
not indicate that it was the same program, so in this case, it is likely that
you already have another copy of Solr running and that copy has the index
directory locked. You cannot access the same index directory from multiple
copies of Solr unless you disable locking, and that would be a REALLY bad idea.
Thanks,
Shawn
