"function not implemented" error occurred when request daemon start. What could this error message be about?

**Problem Description:**
When upgrading from influx 2.7.1 to the recommended influx 2.7.3 version of Influx after the operating system update (OpenBSD 7.5), the following error started to occur.

**Error Log:**
2024-04-22T21:14:22.963796Z info Welcome to InfluxDB {"log_id": "0oivPJSl000", "version": "2.7.3", "commit": "none", "build_date": "2024-04-22T21:14:22Z", "log_level": "info"}
2024-04-22T21:14:22.966590Z error Failed opening bolt {"log_id": "0oivPJSl000", "error": "function not implemented"}

**Daemon Start Command:**
/usr/local/bin/influxd --bolt-path /var/influxdb2/influxd.bolt --engine-path /var/influxdb2/engine --http-bind-address 127.0.0.1:8086 --reporting-disabled --ui-disabled

Begin with the /usr/local/bin/influxd daemon start command and the --bolt-path /var/influxdb2/influxd.bolt setting. Reproduce the startup on OpenBSD 7.5 and trace the “Failed opening bolt” error in the daemon’s startup path. Done means identifying the cause of the “function not implemented” message and documenting or correcting the startup failure.
