I was talking about the local data file cached on the slave, not the file it makes on the master.  It’s the local perl module on the slave that is having the problem when it launches.

Sorry, that’s beyond my knowledge of how the code works (I’m not a programmer).  If finding the local cache file on the slave and removing that doesn’t help, you’ll likely have to wait for more people reading this listserv to be back from their holiday breaks.

If I am recalling correctly, I had to remove an existing data_FPing.cache file in the /opt/smokeping/data directory (your path will probaby be different), and then it worked again. I only have FPing probes, so this may not be the exact file you need to remove.
