ZWE1SV Remains Up even with "Unable to start embedded Tomcat server"

[dkelosky]

I get a startup error Caused by: org.springframework.boot.web.server.WebServerException: Unable to start embedded Tomcat server which followed a message ZWEAM510E Invalid key alias 'localhost'.

I needed to fix my zowe.yaml for the proper alias name; however, I noticed that the STC, ZWE1SV remains active even while services fail to start. Should Zowe services detect this scenario and shutdown automatically with a non-zero return code?

Is the ZWE1SV general started task for the whole Zowe server, or is it a specific service? Also is the service being restarted? Because if yes, we already have somewhere issue to make sure zowe launcher doesn't restart failed services in certain cases that are unrecoverable.

Yes. In my case though, I'm only starting API ML related services, e.g. discovery, gateway, catalog, and ZAAS I believe. Since this startup failure meant that nothing in the Zowe STC was usable, I expected everything to shutdown with an error.

The answer is yes as API ML squad we agree that in this situation the Zowe should stop altogether.

There is already a linked case in the Zowe Launcher - zowe/launcher#95

And other issue touching the problem in API Layer repository - zowe/api-layer#3518

With this stated the issue is related primarily to the Launcher and so I would expand on the issue above or move the issue there.
