503 'Error: connect EADDRNOTAVAIL 127.0.0.1:3000 - Local (127.0.0.1:0)

[Stephen_-_]

I've had this issue come up a couple times now.

I'm using the 3.5.2 conference with CentOS 7 with a modification of the basic example.

The issue I've been having is everything runs fine for maybe days or weeks, but then in the woogeen-app.stdout log it will suddenly show:

503 'Error: connect EADDRNOTAVAIL 127.0.0.1:3000 - Local (127.0.0.1:0)\n    at Object.exports._errnoException (util.js:1020:11)\n    at exports._exceptionWithHostPort (util.js:1043:20)\n    at connect (net.js:892:16)\n    at net.js:1028:7\n    at GetAddrInfoReqWrap.asyncCallback [as callback] (dns.js:62:16)\n    at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:81:10)

POST /createToken/ - - ms - -

And I really don't know what is causing it. The server continues to serve up assets fine, but it just can't create a token.

One time, when I let it run for longer like that, it did show an additional error and completely killed the app. The error was:

assert.js:84

  throw new assert.AssertionError({

  ^

Any ideas what is going on?? :(

I don't understand how 127.0.0.1:3000 can be unavailable... What is that connecting to? Nuve? When I look at the Nuve logs it doesn't end on any errors, it just simply stops logging anything.

When I restart-all.sh the app reboots and begins to work correctly again. When I did this after the server stopped even serving up assets, I noticed it said "no app to stop", which makes me think it's a problem isolated to the app portion.

Sorry I'm not very knowledgable with the server things :\ .
