Hi Steve, I will investigate on my RPI4

Subject: mesh: call to Publish triggers apparent output loop in mesh/mesh-io-generic.c
Publish functions as expected, but results in continuous, very heavy
HCI traffic (~every .7ms per btmon log). I don't think it's my
application as the problem persists after the application disconnects
from dbus and exits.
The calls to LE Set Adv Param all fail. Prior to the Publish call, LE
Set Param calls succeed. The only difference I can see is the failing
ones have an interval of 50ms and the ones that succeed have 100ms. A
successful one is appended.
I'm at current Bluez head (65231892cd). The platform is a rpi4.
Below is a pretty normal looking meshd log, a btmon dump and some more
normal looking dbus traffic.
