---------------------------------------
Another error message before the assert failed:
{code:java}
2024-03-23T08:10:04.623Z ERROR core.rest
webservice/webservice.go:74 HTTP serving error {"error": "listen tcp
:9080: bind: address already in

{code}
This issue also happened in my Ubuntu 23.04 env. (But not in my MacOS 13.3)
It succeeds the first time it runs(make test), but fails in subsequent tests.
So I guess the root cause is there are some stale state/connections remain.
After checked the code, I found that the entrypoint_test.go didn't stop
services in ServiceContext:

And this issue was fixed after I changed it to:
{code:java}
serviceContext := StartAllServices()
defer serviceContext.StopAll(){code}
Hi [~targetoee] Since you're the first one to discover this issue, would you be
willing to take on this fix?
