some clarifications: 

- Do you have any alerts enabled in the Targets section?

- Is the above quote from server A or server B? If from A, please include
  it from server B too. (Server A is not interesting here; it's working
  'well enough' and is an ancient version.)

- When server B stops logging, does the smokeping daemon die or is it
  just doing nothing? Does it recover when the unresponsible devices
  come back?

There are two problems here: the parameters should be tuned so that
you never get the 'smokeping took ... seconds' message, even when
the targets are down, but obviously Smokeping should recover from it.

I don't quite understand why the messages show up in the first place
with the FPing parameters you have, but I'll look into that.

The best help would be the output of 'smokeping --debug-daemon' at 
outage time, but of course I realize that might be a bit hard to get
given the verboseness of it even when everything is OK.

The output of 'smokeping --debug' when everything works would be good 
to have too.
