stuck creating pty?

[risacher]

I have two Ubuntu servers, each running tty.js - one works fine all the time, but the other gets "stuck" after a day or two. The user experience is that when the "Open Terminal" button is clicked, a black window opens but no process is spawned.

Based on the console output where tty.js is running, I speculate this has to do with creating ptys... see below. Observe how for Session 17-18 it immediately reports "Created pty..." but when it stops working properly, it stops saying that (Sessions 19-22).

Anyone seen similar behavior or have ideas how to troubleshoot this? If I restart tty.js, the problem goes away for a day or two.

Disregard; sorry.
I still have an issue, but it ain't with creating a pty. I never get a good socket.io connection after the first session.

Resolution for anyone with similar problem: I was running tty.js behind a reverse-proxy server based on node-http-proxy. Unfortunately, because of http-party/node-http-proxy#444, proxying websockets with node 0.10.x is broken. I solved my problem by switching the proxy server to nginx.
