The VM is a fresh install from the x86_64 ova.

Research direction
Start with the Photon OS 5.0 GA sshd.socket service and the journalctl entry showing signal 15 after a monitoring check on port 22. Reproduce the behavior with the listed monitoring step, then trace why sshd terminates and verify that repeated port checks leave the service running.
