Maybe the ports are temporarily unavailable and we don’t give the chance for them to become available. Adding a restart delay in snap (snapcraft's apps.<app-name>.restart-delay) or to the service (EDGEX_STARTUP_INTERVAL env var) could help.

Got the same error locally. The port wasn't used by any process when I checked but it looks like core-command restarted 10 times within 10 seconds before (systemd) giving up.

It happens again in GitHub action test. core-data port 59880 is busy. There is no restart attempt:

Another solution is to start the failed services manually, while waiting 180 seconds for the them to become available.

Port 44444 is occasionally occupied as well:

Port 44444 is not available: #207 (comment)

We may be able to find the root cause by adding a check before starting services to:
- verify that all expected ports are available
- if not, find the process using that port and print the application name

Since the services are now all disabled by default, we have the chance to set EDGEX_STARTUP_INTERVAL before starting them for the first time, to slow down the restart intervals suggested in #118 (comment). The downside of doing that is the reliance on a feature which gets tested only later on as part of the same testing suite.
