Verify which process actually owns a TCP port before assuming your fresh restart succeeded. Use when: (1) you killed an old server and started a new one but behaviour matches the OLD code/data, (2) pkill -f pattern returned 0 but old behaviour persists, (3) you embedded a new asset/binary but the served version is stale, (4) any "I just restarted X but I'm getting old results" situation. pkill -f matches against the process command line — if the live old process was started with --port 0 (auto-assigned) and got the port you now want, the pattern won't match it. Always verify with lsof -i :PORT before debugging deeper.
