Comment (by robertm):

 In discussion with this user in IRC, we've found that the MBE is sending
 numerous MythEvent SIGNAL events per second to the SBE, which appear to be
 overrunning its ability to keep up and stream content.  Toggling "always
 stream from master backend" to off has preliminarily helped the issue, but
 the "SIGNAL 1" events seem to be causing a problem.  It appears they are
 dispatched from

 void SignalMonitor::MonitorLoop()

 The loop continues and overwhelms the SBE, which then starts spewing
 MythSocket errors, and the frontend is stuck in a loop.

 I've asked the reporter to update the ticket with -v network logs from
 both backends.  Reporter notes that killing the SBE seems to fix the
 issue, but the combination of an SBE + always stream from MBE should at
 least be accounted for, rather than just bringing the system to its knees.
