Things are happy again.
I think I've figured it out, but I don't have a smoking gun, a clean fix, or
a reproducible test case.
I think the problem was that I have servers setup to depend on each other.
Several have good refclocks. As long as most of them are working, everybody
is happy. But if I restart too many of them quickly enough there aren't
enough working systems to get started.
I haven't had a power fail in many months, so that hasn't tested anything. I
don't remember any problems getting going after the last one. I assume I
"fixed" a config file or something.
Now I have to go figure out the minimal set of external servers I can depend
upon. I have a slow DSL line that is a good bufferbloat demo so I'd like the
answer to be null. But I don't trust any single refclock or driver.
There should be something describing this case in our documentation, but I
don't remember seeing it.
These are my opinions. I hate spam.
