Comment(by awithers):

 I’ve attached a patch which should work around one possible route to this.
 It is currently specific to a slave backend being the cause and will not
 be committed until I find a better fix.

 What can happen:

 MBE: scheduler posts a MythEvent("SCHEDULE_CHANGE")

 Loop:
 MBE: MainServer::customEvent() dispatches MythEvent("SCHEDULE_CHANGE") as
 BACKEND_MESSAGE to anyone listening.
 SBE: Receives BACKEND_MESSAGE and resurrects MythEvent("SCHEDULE_CHANGE")
 SBE: MainServer::customEvent() dispatches MythEvent("SCHEDULE_CHANGE") as
 BACKEND_MESSAGE to anyone listening (including the connection to the
 master backend)
 see Loop
