Hi, thanks for the reply. I could be mistaken, but I looked through the scripts, and I don’t think I’m having Fuseki generate a PIDfile since I’m using `systemd`.
Here is my `fuseki.service` file: [Unit] Description=Apache Jena Fuseki [Service] Restart=on-abort Type=simple ExecStart=/srv/data-tier/fuseki/fuseki-server --conf=/srv/data-tier/database/config.ttl --port=31457 User=fuseki SupplementaryGroups=prte_database Environment='FUSEKI_BASE=/srv/data-tier/database' 'FUSEKI_HOME=/srv/data-tier/fuseki' 'JVM_ARGS=-Xmx1500m' [Install] WantedBy=multi-user.target The `fuseki` user owns `/srv/data-tier/database` and has read/write/execute permissions on it. According to the `systemd` docs <https://www.freedesktop.org/software/systemd/man/systemd.service.html#PIDFile=>, if I set `Type=simple` on a service, it shouldn’t be using PIDfiles. Is that the problem? Should I have `Type` set to something else? Best wishes, Noah G.
