If knox gets timeout, node.js server process gets killed

See original GitHub issue

Hope i’m not duplicating anything but when i try to get many files from S3 the server gets killed randomly. It works most of the time but sometimes when a socket fails the whole server is dead.

The error is:

        throw er; // Unhandled 'error' event
Error: read ECONNRESET
    at errnoException (net.js:901:11)
    at TCP.onread (net.js:556:19)

@refaelos No, this issue is caused by an uncaught error event, as noted here:

Error events are treated as a special case in node. If there is no listener for it, then the default action is to print a stack trace and exit the program.

I guess you called putFile without handling the error event as me. The simple fix is to handle it.

var emitter = knoxClient.putFile(...)

emitter.once('error', errorHandler)

Swallowing any errors sounds like a good idea, but I am afraid it might be a bug because I can see the same error twice. Not sure if it’s the same thing as you mentioned in #1
