Hi, It looks like this is a bug that was fixed in later releases. The `path` variable was a null pointer when it was passed to `systemd_unit_exec_with_unit` as the `unit` argument. Commit 62a0d26a <https://github.com/ClusterLabs/pacemaker/commit/62a0d26a8f85fbcee9b56524ea3f1ae0171cbe52#diff-00b989f66499e2081134c17c06d2b359R201> adds a null check to the `path` variable before using it to call `systemd_unit_exec_with_unit`.
I believe pacemaker-1.1.15-11.el7 is the first RHEL pacemaker release that contains the fix. Can you upgrade and see if the issue is resolved?
