you could try the '--debug-daemon' option, it produces lots of debug
information in the log.
Generally it would be best to tune the polling parameters so that
unresponsive devices don't cause any problems. Which probe(s) are you
using? If it's the FPing probe, you have to either increase the 'step'
variable or decrease 'timeout' or 'pings'. If it's one of the others,
you can also increase the 'forks' variable, which controls how many
targets are probed concurrently.
