We shut down the master for 10 mins. The 2 slaves have not updated the gaps in their graphs yet.

I know the version in the deb repos is not up to date, so maybe the newer version will help.

"The slave tries to contact the master server after every round of
probing, supplying its results. If the master server can not be reached,
the results will be sent to the server together with the next round of
results. Results will be stored in a perl storable so that they survive
a restart of the smokeping instance."
