Undefined behaviour in kafka-to-nexus.cxx

Created by: SkyToGround

The signal handler (signal_handler()) in kafka-to-nexus.cxx implements undefined behaviour. A list (that is not complete) of functions that you are allowed to call can be found here: http://man7.org/linux/man-pages/man7/signal-safety.7.html

Note that calling any of the printf family of functions in a signal handler is undefined behaviour.
