Description of problem:
gethostbyaddr leaks a file handle when it cannot look up the address in 
the /etc/hosts file. Placing the ip in question in the hosts file fixes 
the problem, removing it causes the problem.

char * pr_addr(unsigned int addr)
{
        struct hostent *hp;
        static char buf[80];

        //file handle leak occurs right here when addr not in hosts file
        hp = gethostbyaddr((char *)&addr, 4, AF_INET);

        if ( hp == NULL )
                //sprintf(buf, "%s", inet_ntoa(*(struct in_addr *)&addr));
                sprintf(buf,"pr_addr : could not resolve host.\n");
        else
                sprintf(buf, "%s (%s)", hp->h_name,
                        inet_ntoa(*(struct in_addr *)&addr));
        return(buf);
}
