ECONNRESET from Travis?

[jorgenschaefer]

My Travis builds have been failing randomly for the last weeks because evm has trouble downloading images:

Your build has been stopped.

Any idea what might be causing this? It works most of the time, but I have regular build errors because of this.

No idea actually, have never seen this error. It might be a good idea to implement retries (for example http://stackoverflow.com/questions/9204920/how-to-catch-error-connection-reset-by-peer-errnoeconnreset) though.

[rejeep]

Is this still an issue? Anyways, the download mechanism is replaced, so hopefully that'll solve it. Reopen this issue if not.

I have not seen this in a while, so closing is fine with me. I'll come along if I see it again. :-)
