Here an excerpt from the gecko.log:

m64-d-0000000000000000/build/src/embedding/components/windowwatcher/nsWindowWatcher.cpp, line 2186
++DOMWINDOW == 180 (0x12e609400) [pid = 1659] [serial = 609] [outer = 0x12d756800]
1471396903193	Marionette	TRACE	conn904 <- [1,9,null,{"value":null}]
++DOMWINDOW == 181 (0x12cdf1c00) [pid = 1659] [serial = 610] [outer = 0x12d756800]
1471396903497	Marionette	TRACE	conn904 -> [0,10,"getChromeWindowHandles",null]
1471396903499	Marionette	TRACE	conn904 <- [1,10,null,["3","601"]]
1471396903506	Marionette	TRACE	conn904 -> [0,11,"getChromeWindowHandles",null]
1471396903508	Marionette	TRACE	conn904 <- [1,11,null,["3","601"]]
1471396903511	Marionette	TRACE	conn904 -> [0,12,"switchToWindow",{"name":"601"}]
1471396903575	Marionette	DEBUG	loaded listener.js
1471397263532	Marionette	DEBUG	Closed connection conn904

As you can see we send the switchToWindow() command at 1471396903511 and never get a reponse. Then we close the socket connection 360s later. It looks to be similar to bug 1294456.

This should no longer be an issue since the patch on bug 1294456 has been landed.

Moving bug to Testing::Marionette Client and Harness component per bug 1815831.
