Are you using pthreads? Signal handling with the threads is tricky. Is 
SIG_IGN set before child threads are launched?
You should use the pthread interface to handle it.

     int laststate, lasttype;
     sigset_t sigs;

     sigemptyset(&sigs);
     sigaddset(&sigs, SIGPIPE);
     pthread_sigmask(SIG_BLOCK, &sigs, NULL);
     pthread_setcancelstate(PTHREAD_CANCEL_DISABLE, &laststate);
