Shard Lock

Hi All,
We are getting below exception from Solr where 3 zk with 3 solr nodes and 3
replicas. It was working fine and we got this exception unexpectedly.

   -
- *k04o95kz_shard2_replica_n10:*
org.apache.solr.common.SolrException:org.apache.solr.common.SolrException:
   Index dir *'/opt/solr/volumes/data/cores/k04o95kz_shard2_replica_n10/data/index.20201126040543992'
   of core 'k04o95kz_shard2_replica_n10' is already locked. The most likely
   cause is another Solr server (or another solr core in this server) also
   configured to use this directory; other possible causes may be specific to
   lockType: native*
   - *k04o95kz_shard3_replica_n16:
org.apache.solr.common.SolrException:org.apache.solr.common.SolrException:
   Index dir
   '/opt/solr/volumes/data/cores/k04o95kz_shard3_replica_n16/data/index.20201126040544142'
   of core 'k04o95kz_shard3_replica_n16' is already locked. The most likely
   cause is another Solr server (or another solr core in this server) also
   configured to use this directory; other possible causes may be specific to
   lockType: native*

Wild shot here: two Solr instances started on the same data directory?

Best regards,
