Table locks surviving cluster restarts

A table lock caused by a failed truncate will not be cleared even after a complete cluster restart:

Table LockID Process PID Session Txn CreationTime State DBRoots

dm_temp.tablename 1 DDLProc 5444 775 573937 Thu Nov 14 20:17:18 2019 LOADING 1,2

A cleartablelock will probably remove it, but it is not proper behaviour that a tablelock survives a cluster restart.
The table remains locked, affecting normal production workflow as data can't be inserted until the lock is cleared.
