The engine hangs on start-up

[gordonab]

In the process of testing the VU command changes and I can't get the engine to start without hanging. It gets to the info: Connecting to G2... most of the time and made it to info: Configuring G2 once. An error message is returned if I wait long enough:

events.js:72 throw er; // Unhandled 'error' event

But, I can't locate the events.js to try and fix the issue.

[ryansturmer]

Events.js is a node internal library... the error isn't actually there. Can you set the log_level to 'debug' in config/data/engine.json and send me the output?

[gordonab]

Thanks for the detailed instructions. Here is the output when attempting to start the server. Let me know if you need me to try anything.

[jlucidar]

the web server doesn't start, anything running on port 8080 ? Ryan, did you change the port with the new settings stuff ?

[ryansturmer]

i'm back in town and looking at this now, guys. Sorry for the delay.

The default port is 9876 now, since the detection server defaults to 8080 - was this your intent, jimmy?

[ryansturmer]

@gordonab

I bet this is a bug we've seen before.

Go to the config directory, and under both default and data remove the configuration setting for st - you are using an older G2 firmware that doesn't support setting the switch type, and I think that it's crashing the system.

[jlucidar]

yes, that's probably the problem (the st setting). I will remove it from the master branch. For the port, Windows show display a popup asking if you allow the engine to uset. the default port should be configurable. I used 8080 on all my systems, but If you try to run the dashboard on the same computer, you need to have two distinct ports. That's probably why I put 9876 (even if I don't remember doing it ...)

[gordonab]

Getting rid of the ST in the G2 file worked, as well as changing the address to 9876. Is the later going to be a permanent change or is it going back to 8080?

[jlucidar]

We didn't really decide what the port numbers will be ... We should start a discussion on it, ...
