Add waitpid() when recorders are destroyed for avoiding zombie processes. When udp_port is inappropriate, a parent process will destroy all child recorder processes. Currently, the process does not wait for the termination of the children, so those recorders can become zombie processes if the parent process cannot die at once due to any reasons.
