+I've stumble across this issue while running mariadb server in VM Guest.\\
+I believe this happens sometime when VDP is doing backup or machine is being migrated by DRS.
+In my case, i've enable innodb per tables. So i've to clear lock from all files in subfolder.\\
+In order to fix the issue, following command usually fix the issue.
+<code bash>
+systemctl stop mariadb
+cd /var/lib/mysql
+for i in `find . -name '*.ibd'`; do mv $i $i.bk; cp -a $i.bk $i ; rm $i.bk ; done
+systemctl start mariadb
