This line by itself is enough to cause undefined behavior. There is very little that you can do from a signal handler; accessing global objects such as cout is a VERY bad idea.
the program works fine and responds to messages. however I get the following error when i press CTRL-C
mysql_dealer: /usr/local/include/boost-1_39/boost/thread/pthread/mutex.hpp:45: boost::mutex::~mutex(): Assertion `!pthread_mutex_destroy(&m)' failed.
any help would be much appreciated.
What most probably happens is that the destructor is attempting to destroy the mutex while it is held locked by another thread. You will need to devise a better shutdown strategy.
