tdb2.tdbcompact command line tool returns Failed to get a lock: file

I'm running apache-jena-fuseki-3.13-1 and just found tdb2.tdbcompact from its bin-directory. I should run tdb2.tdbcompact nightly to prevent my jena-fuseki from running out of disk space, but now I get error message( Failed to get a lock: file) when running it:

miettinj@ramen:~/jena> ./apache-jena-3.13.1/bin/tdb2.tdbcompact --loc=./apache-jena-fuseki-                        3.13.1/run/databases/test_TDB2
org.apache.jena.dboe.DBOpEnvException: Failed to get a lock: file='/srv/work/miettinj/jena/apache-jena-fuseki-3.13.1/run/databases/test_TDB2/tdb.lock': held by process 6136

"held by process 6136"

Another process is using the database. Compaction has to happen from the process using the database.

Apache Jena Fuseki Jena 3.17.0 added a function endpoint so that the administrator can ask for compaction on a running Fuseki server.
