Comment (by cohosh):

 Hey, I'm working on reproducing this bug and after investigating these log
 messages from above:
 {{{
 2017/01/24 13:35:16 Traffic Bytes (in|out): 749 | 218 -- (1 OnMessages, 1
 Sends)
 2017/01/24 13:35:23 Traffic Bytes (in|out): 4803 | 3907 -- (8 OnMessages,
 7 Sends)
 }}}
 It looks like your client is actually sending and receiving bytes
 correctly.

 So when you were in this connect/close loop, were you unable to send and
 receive traffic? Or is this just usual behaviour like in #25429?
