panic: websocket: close 1006 (abnormal closure): unexpected EOF

[jsdevel]

Periodically I see this error in my terminal and my connection closes:

panic: websocket: close 1006 (abnormal closure): unexpected EOF

goroutine 1 [running]:
main.(*WebTerm).Run(0xc4201ed8a0)
	/home/jsdevel/.gvm/pkgsets/go1.8/global/src/github.com/fangli/rancherssh/main.go:141 +0x13c
main.main()
	/home/jsdevel/.gvm/pkgsets/go1.8/global/src/github.com/fangli/rancherssh/main.go:308 +0x11d

This same behavior exists in the web UI shell when I have a long running process that neglects stdout. Anytime a process logs to stdout on a frequent basis I don't have this problem. Could there be a setting I need to set in rancher?

Possible solution here.

The cattle machines I'm connecting to reside behind ELB which has a default idle timeout of 60 seconds. Increasing the timeout there isn't really an option because it also means opening up the timeout for HTTP requests as well which I don't want.

Is is possible for rancherssh to "tickle" the connection to keep it open? Perhaps send a null character every 10 seconds or so?
